Answer 2

Answer:

Electropolishing

Explanation:

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.[1] It may be used in lieu of abrasive fine polishing in microstructural preparation.
