At present, in the bicycle industry, especially in the high-end bicycle industry, people are increasingly pursuing high-quality driving experience, and require bicycles to be safe, reliable, and light. Titanium bicycles are high-end bicycles that have become popular in the world. In order to further To lighten the weight of the vehicle body, the manufacturer hopes to change the frame tube from a straight tube with equal diameter to a tube with a variable inner diameter and wall thickness. The characteristic of this kind of pipe is that the outer diameter is constant, and the inner diameter is small at both ends and large in the middle, so it is difficult to produce this kind of titanium welded tube. According to the needs of users, a new technology was used for trial production. After nearly a year of hard work, the trial production was successful and samples were provided to foreign manufacturers. Now, has designed and manufactured a special machine tool that can mass-produce such pipes. Under the control of the computer, it can produce different specifications of inner diameter reducing pipes and realize industrialization.

Titanium is prone to crevice corrosion in some media
Titanium is prone to crevice corrosion in some media. Structural design should eliminate gaps and recesses that can store water as much as possible. The gap between the titanium plate and the titanium plate is also susceptible to corrosion, especially the gap formed by titanium and tetrafluoroethylene. Because titanium is not corrosion-resistant to solutions containing a small amount of soluble fluoride, fluoride causes passivation damage. Therefore, special care should be taken when using PTFE plastic gaskets, fluorine-containing rubber gaskets and adhesives. Its strength index decreases with the increase of temperature, and the mechanical properties of titanium change with temperature. For example, the tensile strength and yield strength at 250 to 300 ° C are half of those at room temperature. Even when the design temperature is not high, therefore. It should also be selected according to the strength value at the design temperature. grade 2 titanium sheet has a high yield ratio and good durability. When the design temperature is below 316°C, the tensile strength value at this temperature is often what determines the design strength index. For industrial pure titanium, the strength index value cannot be improved by heat treatment. When Titanium Threaded Forged Fitting is used in combination with other materials, the thermal expansion coefficient of titanium is small. Pay attention to the stress caused by the expansion difference.

Treatment of surface defects after titanium forgings are made into parts
Since titanium forgings are made into parts, their stress, importance, and working conditions are different during use, and their materials and metallurgical processes are also different. Therefore, different parts are divided into titanium forgings according to the above conditions and in accordance with the requirements of this department. In terms of categories, different departments and different standards classify titanium forgings differently. But in any case, the quality inspection of titanium forgings as a whole is inseparable from two types of inspections, namely the inspection of appearance quality and internal quality, but the categories of titanium forgings are different, and the specific inspection items, inspection quantities and inspection requirements Just different. For example, some industrial departments classify structural steel, stainless steel, and heat-resistant steel F9 Titanium Forging into Class IV for inspection; some departments classify aluminum alloy titanium forgings and die titanium forgings Aluminum alloy and copper alloy titanium forgings are divided into category IV for inspection.
Specifically, the appearance quality inspection of titanium forgings is to check whether the shape and geometric dimensions of titanium forgings meet the requirements of the drawing, whether there are defects on the surface of titanium forgings, what kind of defects are, and what are their morphological characteristics. The inspection content of the surface state is generally to check whether there are surface cracks, folds, wrinkles, pressure pits, orange peel, blisters, scars, corrosion pits, bruises, foreign objects, underfilling, pits, lack of meat, etc. on the surface of titanium forgings. Defects such as scratches. The internal quality inspection is to check the internal quality of the titanium forging itself, which is a quality condition that cannot be found in the appearance quality inspection. It includes not only checking the internal defects of the titanium forging, but also checking the mechanical properties of the titanium forging, and for important and key parts. Or large titanium alloy forged rings should also be analyzed for chemical composition. For internal defects, we will use low-magnification inspection, fracture inspection, and high-magnification inspection to check whether titanium forgings have internal cracks, shrinkage cavities, porosity, coarse grains, white spots, dendrites, streamlines that do not conform to the shape, streamlines, etc. Defects such as disorder, flow-through, coarse-grain ring, oxide film, delamination, overheating, and overfired tissue. As for the mechanical properties, it is mainly to check the tensile strength at room temperature, plasticity, toughness, hardness, fatigue strength, high temperature instantaneous fracture strength, high temperature durable strength, durable plasticity and high temperature creep strength, etc.
The existence of defects in titanium forgings, some will affect the quality of subsequent processes or processing, and some will seriously affect the performance and use of titanium forgings, and even greatly reduce the service life of finished products, endangering safety. Therefore, in order to ensure or improve the quality of titanium forgings, in addition to strengthening quality control in the process and taking corresponding measures to prevent the occurrence of titanium forging defects, necessary quality inspections should also be carried out to prevent subsequent processes (such as heat treatment, surface treatment, Cold working) and titanium forgings with defects that have adverse effects on performance flow into subsequent processes. After the quality inspection, remedial measures can also be taken for the manufactured titanium forgings according to the nature of the defects and the extent to which they affect the use, so as to make them meet the technical standards or use requirements.
Therefore, in a sense, the quality inspection of titanium forgings, on the one hand, is to check the quality of titanium forgings that have been produced, and on the other hand, it is to point out the direction of improvement for the forging process, so as to ensure that the quality of titanium forgings meets the requirements of titanium forgings technical standards. And meet the requirements of design, processing and use. The quality inspection of titanium forgings includes the inspection of appearance quality and internal quality. Appearance quality inspection mainly refers to the inspection of geometric dimensions, shapes, surface conditions and other items of titanium forgings; internal quality inspection mainly refers to the inspection of chemical composition, macrostructure, microstructure and mechanical properties of titanium forgings.

How to deal with the surface of the titanium tube?
The alloying of the surface of the titanium tube can also be called a coating. Compared with the oxide coating of palladium coated on titanium, it has the advantages of strong bonding, wear resistance and corrosion resistance. Compared with titanium-palladium alloy, the surface content of palladium is high, which saves the precious metal palladium, reduces the cost, and also has excellent performance.
Aluminizing the surface of the Titanium Coil Tube can reduce the tendency of titanium to absorb hydrogen. Mixing 88% alumina, 4% aluminum fluoride and 8% aluminum powder and coating it on the titanium workpiece is the best aluminizing condition. The temperature is 810°C . The thickness and structure of the aluminized layer depend on the holding time. Using the cladding aluminizing method, a thin coating about 2 mm thick can be obtained by short-term diffusion, which has good bonding force and does not affect the mechanical properties of the substrate. The coating consists mainly of a titanium oxide phase, forming a very effective barrier against hydrogen permeation.
After the palladium plating on the Titanium Condenser Tubes, it can be heated by different methods to diffuse the palladium plating layer to the surface area of the titanium tube to form a titanium-palladium alloyed layer on the surface, thereby improving the corrosion resistance. Thermal diffusion or laser surface remelting are possible in principle. Use the laser to irradiate the titanium surface to make it melt and condense rapidly, so that the pre-vacuum-deposited 150-micron palladium film can be rapidly melted to form an effective palladium alloy.

Titanium tube has excellent high temperature and low temperature performance
titanium seamless tubings have excellent high and low temperature performance. Seamless titanium tubes can still maintain good mechanical properties at high temperatures, and their heat resistance is higher than that of aluminum alloys, and the operating temperature range is wider. At present, the operating temperature of new heat-resistant titanium alloys can reach 550-600 ° C; At low temperature, the strength of titanium alloy is increased than that at normal temperature, and it has good toughness. Low-temperature titanium alloy can maintain good toughness at -253°C.
When the titanium bicycle tubing is used, the lower opening of the outer tube is usually connected to the faucet, because the water will automatically flow upward when it is heated in the condenser tube, so as to achieve a greater cooling effect. Jinxi Titanium Industry Technology Co., Ltd. is committed to providing better quality titanium tubes. Titanium welded tubes serve as high-quality products for refrigeration equipment condensers.

Experience Introduction of Processing Methods for Titanium Alloy Materials
The pressure processing of titanium alloys has more similarities with steel processing than with the processing of non-ferrous metals and alloys. Many process parameters of grade 5 titanium round rod in forging, volume stamping and plate stamping are close to those of steel processing. But there are also some important features that must be paid attention to when press working titanium and titanium alloys.
Due to titanium's heat resistance, cooling is critical during titanium alloy machining. The purpose of cooling is to keep the cutting edge and tool surface from overheating. Use end coolant for excellent chip evacuation when shoulder milling as well as face milling pockets, pockets or full slots. When cutting Seamless Titanium Tube Grade 2, chips can easily stick to the cutting edge, causing the next round of milling cutter rotation to cut chips again, often causing edge line chipping. Each insert cavity has its own coolant hole/injection to solve this problem and enhance constant edge performance. Another clever solution is threaded cooling holes. Long edge milling cutters have many inserts. Applying coolant to each hole requires high pump capacity and pressure. But it is different, it can block the unnecessary holes according to the needs, so as to maximize the liquid flow to the required holes.

Cleaning process of titanium alloy forging
The oxide scale and α-shell layer formed during the forging heat treatment of all titanium alloys are very brittle, and induce cracks in the subsequent forging or in the final forging or cause tool wear in the subsequent machining process. Therefore, it is recommended that titanium alloy processing remove scale and α-shells between continuous forgings, and scales and α-shells must be removed before forgings are delivered to users.
The cleaning technology of F9 Titanium Forgings has two aspects: one is the removal of oxide skin; the other is the removal of α shell. The scale can be removed mechanically, such as sandblasting; or chemically, such as molten salt derusting. The choice of rust removal method depends on the size, complexity and cost of the part.
Sandblasting is an effective method to remove rust scales. It can remove scales with a thickness of 0.13-0.76mm. It can use 100-150 mesh zircon sand or steel sand, and the air pressure can reach 275Pa. Although sand blasting is available for forgings of various sizes, it is mostly used for medium and large titanium alloy forgings. Sandblasting equipment can use abrasive drums, shot peening or sandblasting units. After sandblasting, it is pickled to remove the alpha shell.
Molten salt derusting is another effective method for removing scale, and pickling removes the alpha shell along with it. 1. The flow chart of rust removal and pickling by molten salt, solution composition and related parameters. The frame used for molten salt derusting is generally made of wood, titanium or stainless steel, in order to prevent electric potential from being generated between the workpiece and the frame, resulting in electrical erosion or arcing of the workpiece. Molten salt derusting is often used for medium and small forgings. In the case of large batches of forgings, the operating system can be fully automated.

What are the methods of cleaning titanium tubes?
Titanium tubes are light in weight, high in strength and superior in mechanical properties. Titanium tubes are widely used in heat exchange equipment, such as shell and tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and pipelines. Many nuclear power industries use titanium tubes as standard tubes for their units. Huayu titanium tube manufacturer took us to see what are the methods of cleaning titanium heat exchanger tubing?
1. Alkaline cleaning: Soak the titanium tube with 3-5% sodium hydroxide analytically pure solution for 30-60 minutes at a temperature of about 40 degrees. Good in an ultrasonic cleaner. After immersion, flush the inside and outside with filtered deionized water or water for injection until neutral, and measure the conductivity. Blow dry with pure air ≥ 0.4Mpa pressure.
2. Pickling: Soak the Seamless Titanium Tube Grade 2 in 5% nitric acid solution for more than 8 hours at a temperature of 40 degrees. Good in an ultrasonic cleaner. After immersion, flush the inside and outside with filtered deionized water or water for injection until neutral, and measure the conductivity. Blow dry with pure air ≥ 0.4Mpa pressure.
3. The above two methods can be used alone or in conjunction with each other. If conditions permit, it can be combined with an ultrasonic cleaning machine for good results.
4. Organic matter pollution can be cleaned in combination with surfactants, and the debris pollution system combined with enzyme cleaning has a good effect.

Titanium alloy wear-resistant composite treatment technology
At present, driven by the growing industrial demand, composite coating technology will gradually replace single coating technology. Micro-arc oxidation is also called micro-plasma oxidation. This technology can prepare ceramic layers with good metallurgical properties on the surface of light metals Al, Mg, Ti and corresponding alloys with the help of high voltage, high current and instantaneous high temperature. The main component of the ceramic layer is the oxide grown in situ on the substrate, and the electrolyte components will also participate in the micro-arc oxidation film layer. The electrical parameters in the micro-arc oxidation process (such as solution formulation, voltage and current, duty cycle, pulse frequency, etc.) have a great influence on the preparation and microstructure of the micro-arc oxidation film. This method has the advantages of safe process, simple operation, and environment-friendly solution. It also has the advantages of simple process, uniform and dense film layer, and less restrictions on the size of workpieces, which cannot be compared with other treatment technologies.
ASTM F136 6Al-4V ELI Titanium Bar alloy micro-arc oxidation film has the advantages of high hardness, high bonding strength of film base, corrosion resistance and wear resistance, but the surface of the film layer is rough, loose and porous, and the friction coefficient is large, which reduces the wear resistance of the film layer. , which shortens the service life of the oxide film, which is not conducive to the application of titanium alloys in abrasive environments. At present, some research institutes of the Russian Academy of Sciences have carried out a lot of work to improve the defect of titanium alloy micro-arc oxidation film, but domestic attention to this issue has just started.

What are the common problems in the process of titanium alloy processing?
Titanium alloy has the characteristics of high strength, small specific gravity, corrosion resistance, low temperature resistance and high temperature resistance. According to the structure after annealing, it can be divided into α-phase titanium alloy, β-phase titanium alloy, and α-β-phase titanium alloy. The α-phase titanium rectangular bar alloy (TA type) cannot be strengthened by heat treatment, so the room temperature performance is not high, it has medium plasticity, and the machinability is acceptable. The β-phase Grade 3 Pure Titanium Sheet alloy can obtain higher room temperature performance through quenching and aging treatment. When α β phase titanium alloy (TC type) is processed, the contact length between the chip and the front is short, and the cutting force acts near the cutting edge. Due to the small thermal conductivity, the temperature of the cutting edge is high, which accelerates the wear of the drill bit, and due to work hardening The phenomenon is more serious, and the elastic coefficient is smaller, so the shrinkage of the drilled hole is larger, which also affects the life of the drill bit.
