Anodising is a process of fomring a thick oxide layer of aluminum. Aluminium develps a thin oxide layer when exposed to air. This aluminium oxide coat makes it resistant ot further corrsoion. the resistane can be improved by making the oxide layer thicker. In this technique aluminium article is used as a anode. Electrolyte used is dilute sulphuric acid. The anode reaction results in formation of a black coloured thin flim of anode. By putting appropriate dyes in the elctrolytic bath coloured surface with decorative finish can be achieved. Kitchen articels like anodises pressure cooker, anodised pans and also frames of sliding windows are the applications fo anodising techniques.
How can use this technique to obtain articles for decorative purpose ?

Text Solution

Verified by Experts

By adding appropriate dyes in the electrolytic bath, we can obtain decorative finish for the articles which cane be used for decorative purpose.
