Surface finish after nickel plating
Surface finish after nickel plating
(OP)
Can someone explain the expected change in surface finish after a part is subjected to electroless nickel plating?
I would expect the finish to measure a bit rougher.

What about any type of plating and surface finish?
RE: Surface finish after nickel plating
With electroless nickel, probably slightly smooths a rough finish and slightly roughens a superfine finish.
Also, pre-plating can include etching or polishing treatments.
Anodizing definitely roughens surfaces, but only usually measurable with hard anodize.

My experience with EN is that with smooth machined surfaces (better than 20microinch) the plated surface had a distinct texture. Not only was it slightly rougher, but it was almost stippled or bumpy. When we had a rough irregular surface (like a sand casting) the plated finish was a little smoother.
We were not doing anything to try and control the surface or the looks. This was just to protect parts.
