what is anodising process
Answers
Answer:
Anodising process
Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium.
Explanation:
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
