(a) Name two metals that resist corrosion due to the formation of a thin, hard and impervious layer of oxide on their surface. (b) Name five methods of preventing rusting of iron. (c) What are the constituents of stainless steel? What are the special properties of stainless steel?

Solution:

(a) Aluminium and zinc are corrosion-resistant metals.

(b) (i) Painting.

(ii) Grease or oil application.

(iii) Galvanization.

(iv) Plating with tin and chromium.

(v) Stainless steel is made via alloying.

(c) Iron, chromium, and nickel are all present in stainless steel.

It has enough strength and does not rust.
