Question

Is nickel deposited on surface of iron to prevent it from rusting

Answer 1

Dear student,

Yes, it is known as Surface plating. It is an anticorrosion treatment. It involves the deposition of nickel or chromium.
Nickel and chromium doesn’t contain iron, they aren’t susceptible to rusting. Surface plating is a more complex anti-corrosion treatment, but it’s highly effective at protecting iron from rusting.
