What Is Anodizing

Dear Ananya,

  •  Anodizing is an electrochemical process of forming a thick layer of Aluminium oxide on top of Aluminium.
  • Aluminium develops a thin oxide layer when exposed to air.
  • This Aluminium oxide coat makes it resistant to corrosion .
  • During anodizing, a clean aluminium article is made the anode and is electrolysed with dilute Sulphuric Acid. The oxygen evolved at the anode reacts with aluminium to make a thick protective oxide layer.
  • This oxide layer gives aluminium articles an attractive finish.
