The surface roughness of the workpiece surface after chromium plating has a direct relationship with the following conditions:
1. The surface roughness of the substrate before plating: the smaller the value of the surface roughness of the substrate, the smaller the value of the surface roughness after plating;
2. The temperature of the plating solution: high temperature plating surface roughness value will be large;
3. The size of the current density: the greater the current density after plating surface roughness value is large;
4. The concentration of plating solution: plating solution concentration is large plating surface roughness value is large;
5. Plating time: the longer the plating time, the greater the value of surface roughness after plating.
Decorative chrome plating before and after plating surface roughness value difference is not big, hard chrome plating before and after plating surface roughness value difference is big.
