Question

What is Anodizing? Explain in brief?

Answer 1

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish

Answer 2

Anodising is a process of forming a thick oxide layer of aluminium.Aluminium develops a thin oxide layer when exposed to air.This aluminium oxide coat makes it resistant to further corrosion.The resistance can be improved by making the oxide layer thicker.In this technique aluminium article is used as an anode.Electrolyte used is dilute sulphuric acid.The anode reaction results in formation of a black coloured thin film of aluminium oxide on the surface of anode.By putting appropriate dyes in electrolytic bath,coloured surface with decorative finish can be achieved.Kitchen articles like anodised pressure cookers,anodised pans and also frames of sliding windows r the appliances of anodising technique....
