"Surface roughness after hard chrome plating"
April 19, 2010
We are doing hard chrome plating (15 to 20 microns thickness) and after a electropolishing process in our bearing component.
We are able to achieve surface finish (Rt) of 0.50 microns before plating process that is in the substrate.
1. Will the achieved substrate surface finish(Rt) will increase or decrease after hard chrome plating.
2. Mentioned surface finish Rt is the total roughness in the measured surface before plating. After hard chrome plating, the same surface will be coated to 15 to 20 microns. Will the surface finish Rt - 0.5 microns will be filled by the hard chrome plating thickness of 15 to 20 microns.
If the chrome fills the substrates surface, is it the surface roughness depends only on the chrome structure.
