Question

give some methods for protecting metals from corrosion ?​

Answer 1

Explanation:

The corrosion of metals can be prevented in the many ways like some of them are :-

$\rule{200}{1}$

$\boxed{\underline{\bold{\mathsf{By\:surface\:coating\:}}}}$

$\implies$ By applying oil grease, paint , etc on the surface.

$\implies$ by galvanization that is the process of coating a layer of zinc over the surface of the metal which helps in the prevention of corrosion of iron.

$\rule{200}{1}$

$\implies$$\boxed{\underline{\bold{\mathsf{\:Using\:Anti-rust\:solutions\:}}}}$:—

That is solution of Alkaline phosphate and alkaline chromate are generally used as the anti rust solutions.

$\boxed{\bold{\mathsf{\:by\:forming\:in-soluble\:phosphate\:}}}$

$\bold{\mathsf{or\:chromate\:coating\:on\:the\:surface\:of\:the\:metal}}$:-

$\implies$ In this process the metal surfaces are treated with the phosphoric acid to form an insoluble phosphate.

$\implies$The formation of Tin Chromate layer also prevents the corrosion of metals.
