Electropolishing & Mechanical Polishing

About

Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish. It is used to polish, passivate, and deburr metal parts. It is often described as the reverse of electroplating. It may be used in lieu of abrasive fine polishing in microstructural preparation.

 

Mechanical polishing is the smoothing of a surface using mechanical tools and abrasives. Mechanical polishing is performed in steps with progressively finer abrasives until a desired smoothness is achieved. The precision polishing process removes material and plastically deforms the surface while it alters the macroscopic and microscopic surface texture.
