Does electroless nickel decrease surface finish? Yes. Generally it decreases surface finish by about half, so if you are aiming for a final surface finish of 16rms, the pre-plate surface finish should be 8rms. Why are the thickness requirements so high for severe service conditions in electroless nickel specifications such as SAE AMS 2404?
