At present, the valves commonly used in most industries are metal valves. The use of metal valves has been around for hundreds of years. Although it has been improved by structure and materials, it is more and more unable to adapt to the needs of harsh conditions such as high wear and strong corrosion due to the limitations of metal materials. The shortcomings of the traditional metal industrial valves are mainly reflected in the short service life and serious leakage, which greatly affects the stability of the system operation. These valves are in urgent need of radical innovation in materials, design and manufacturing processes. As a new material in the…
