Electropolishing

Finish Name

Electropolishing
Electrochemical polishing
Anodic or Electrolytic polishing

Specification

ASTM-B912

Benefit

Electropolishing uses current flow in a chemical bath to smooth a metal surface by removing surface material. It reduces the surface roughness by preferentially eroding micro-peaks. It is used to passivate (make the surface less reactive), and deburr metal parts.  The end result is a very clean and smooth finish.

Base metal substrate

Stainless steel alloys
