explain anodizing process in detail
Answers
Anodizing (also spelled anodising in British English) is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell.

Anodizing is a method of increasing the corrosion resistance of a metal part by forming a layer of oxide on its surface. The part that is being treated forms the anode electrode of an electrical circuit. Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does.
Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thick transparent coatings that add interference effects to reflect light. One example of the latter is equipment used by cyclists on gear or clothing so they can be seen at night.
