Answer 2

Answer:

itis a process of forming a thick oxide layer on the surface of aluminium aluminium develop a thin layer of oxide when left in air this oxide layer is protective and prevent the metal from for the oxidation this layer can be made more thick by anodizing the process clean aluminium article is taken as anode and H2 s o4 as an electrolyte when electric current is passed O2 gas get liberated which react with metal aluminium to form a thick layer of oxide on its surface
