Answer 1

Explanation:

Use an Alloy: The use of alloys, like stainless steel, is one of the most common ways to prevent rust, or slow it down. ... Galvanize: Galvanizing coats iron or steel in zinc to protect from rust. Zinc corrodes at a much slower rate than iron or steel, so it's highly effective for slowing rust.

Answer 2

The reddish brittle coating formed on iron especially when chemically attacked by moist air and composed essentially of hydrated ferric oxide.The rusting of iron can be prevented by painting, oiling, greasing or varnishing its surface. (2) Galvanisation is another method of protecting iron from rusting by coating iron with a thin layer of zinc. (3) Corrosion of iron is prevented by coating iron with non-xcorrosive substance like carbon
