A significant feature of the titanium plate is its strong corrosion resistance. This is because it has a particularly strong affinity for oxygen and can form a dense oxide film on its surface, which can protect titanium from corrosion by the medium. , Neutral salt solution has good stability in neutralizing oxidizing medium, and it has better corrosion resistance than existing stainless steel and other commonly used non-ferrous metals, and even comparable to platinum.
The quality of the titanium plate is largely determined by the smelting process, including the chemical composition of the titanium, the cleanliness of the titanium water (gas, harmful elements, inclusions) and the quality of the casting (component segregation, decarburization and surface conditions) These aspects are the key control points of smelting operations. In addition, industrial titanium plates also require sufficient hardenability to ensure uniform microstructure and mechanical properties across the spring section. The main cause of fatigue cracks in the oxide inclusions in titanium and the damage of type D inclusions to fatigue life is greater than that of type B inclusions. Therefore, foreign titanium factories and automobile factories have put forward higher requirements for oxide inclusions in industrial titanium plates. In particular, Al2O3 and TiN inclusions are the most harmful to the fatigue life of titanium springs. In order to produce high-quality industrial titanium plates, special smelting methods such as electric furnace-electro slag remelting or vacuum arc remelting are usually used in the past.
