The process applications of chrome plating on the surface of the engine valve mainly include the following:

1. Improve wear resistance

The chrome plating layer has high hardness and can significantly enhance the wear resistance of the valve surface, extending its service life.

2. Enhance corrosion resistance

The chromium layer has good corrosion resistance and can effectively prevent damage to the valve in high temperature and corrosive environments.

3. Reduce the coefficient of friction

The chrome plated layer has a smooth surface, which can reduce friction between the valve and seat ring and improve engine efficiency.

4. Improve thermal conductivity

The chromium layer helps the valve to dissipate heat better and prevent deformation or damage caused by overheating.

5. Improve sealing performance

The chrome plating layer makes the contact surface between the valve and the seat ring tighter, enhances sealing, and prevents gas leakage.

6. Extend the service life

Taking into account the above advantages, chrome plating technology can significantly extend the service life of valves and reduce maintenance requirements.
