What are the factors that affect the chromium plating effect of vacuum coating equipment?

When the vacuum coating machine is chrome-plating, many factors will affect the electroplating effect, so what factors affect the chrome-plating effect?

1. The surface roughness of the substrate before electroplating: the smaller the surface roughness value of the substrate, the smaller the surface roughness value after electroplating;

2. High bath temperature: the surface roughness value after electroplating is large;

3. Current density: the greater the current density, the higher the surface roughness;

4. Plating solution concentration: the surface roughness value is larger when the concentration of the plating solution is large;

5. Electroplating time: the longer the electroplating time, the greater the surface roughness value.

Therefore, in the vacuum coating process of electroplating equipment, these factors will affect the effect of electroplating.
