Passivation removes contaminants such as free iron and promotes a protective oxide layer on stainless steel. Electropolishing removes surface material electrochemically, smoothing the surface and helping improve corrosion resistance.
Electropolishing Overview
Electropolishing is an electrochemical finishing process that removes a thin layer of metal through anodic dissolution. It smooths and brightens the surface and can help remove fine burrs and surface contaminants. Used after machining, welding, or other manufacturing processes, it can improve surface cleanliness and corrosion resistance. The result depends on the material, part geometry, and starting surface.
- Smooth appearance:
Electropolishing produces a bright, smooth surface.
- Corrosion resistance:
Removing surface imperfections can help improve corrosion resistance.
- Surface cleanliness:
The process helps remove surface contaminants and creates a surface that is easier to clean.
- Fine deburring:
Electropolishing can help remove fine burrs from metal parts.
