Electropolishing of
Stainless Steel

Among the preplate finishing services offered by Master Finish Company is electropolishing. Often called reverse plating, electropolishing removes a variety of surface contaminants from the surface of stainless steel, leaving behind a higher concentration of nickel and chromium molecules at the part surface. Electropolishing works hardest on the micro peaks of the surface providing a smother, brighter surface. This finishing process improves corrosion resistance and the appearance of the part.

Electropolishing works by an electro-chemical reaction in which metal dissolves faster at surface micro peaks, creating a leveling effect on the surface of the work piece. This process makes electropolishing an excellent option for deburring and general preparation of stainless steel surfaces prior to plating.
