Due to the long-term corrosion and erosion of various chemical substances in the semiconductor precision parts ball valve, and it is easy to receive extrusion and friction during use, after a period of use, the surface of the ball valve will appear wear marks and cracks on the surface in order to improve the ball valve, so this seriously affects the tightness of the ball valve.
How to improve the scratch resistance and high hardness of the surface of the ball valve?
The ball valve processing plant was foundWCC coating plantHoping to help solve this problem, the WCC coating is a tungsten-doped hydrogen-containing amorphous carbon (A-C:H:W) DLC coating. Compared to other elements, this oneW-DLC coatingThe number is lower (usually 0. in the dry case.)1 02), resulting in excellent wear resistance and excellent resistance to rotational contact fatigue. This type of W-DLC coating is produced with a typical deposition temperature of less than 160°C and can complete its coating process without softening heat-sensitive steels such as 100Cr6. It can make the ball valve have self-lubrication, and the coefficient of friction is small, the hardness is high, the finish is high, and the scratch resistance is very strong, so it is the most suitable choice.
We also did research and plated the surface of the ball valveWCC undercoatingAfter that, the cracks, dilution rate and hardness research results in the work show that with the increase of WCC content, the hardness of the coating is significantly improved, the dilution rate is gradually reduced, and the surface will not often be affected by wear marks and cracks, and the service life of the ball valve is significantly increased by 3-4 times after the WCC film layer is added to the surface, which greatly reduces the production cost of the replacement of important parts and improves its production efficiency.
