Wet-chemical surface treatment processes

Wet-chemical surface treatment processes

Electro polishing is an electrochemical process, used to polish, passivate, and deburr metal parts.

 

ProcessObjectivePossible base materials
Electropolishing / Electropolish-deburring
  • Leveling and smoothing rough surfaces
  • Reducing residual tensile and compressive stresses near the material surface
  • Removing cracks near the surface and material inhomogeneities
  • Improving fatigue behavior
  • Opening cracks in preparation for crack test
  • Cr, CrNi steels
  • Ni and Co alloys
