As a rare metal element, titanium's performance is far beyond what we have seen. General power generation equipment, especially the side with a lower thermal cycle temperature, provides an ideal environment for titanium.
It is possible to develop a new type of titanium tube that can be used at a higher working temperature. Compared with the high-strength low-temperature titanium tube that has been developed, it will have greater potential in saving metal and improving efficiency. The goal is to develop a titanium tube that can be used at a temperature of 650°C. This alloy can be used on high-pressure turbine wheels and can reduce weight by 20% compared to the commonly used base wheels.
However, with the increase of working temperature, titanium tubes will inevitably bring more new problems, such as surface oxidation, long-term stability of mass metallurgical production, friction corrosion, fire hazard, and hot salt stress corrosion. Some problems can be solved by surface coating or surface treatment. For this reason, research in this area is currently being actively carried out.
