Question

Galvanisation is a process to prevent rusting of iron.Why is “zinc metal” used for galvanization? Which other method can be used to prevent rusting? Explain.​

Answer 1

Answer:

1.One of the methods to prevent rusting is galvanization. We can use a thin layer of zinc to coat objects of iron (or) steel. This could stop/avoid oxygen and water reaching the metal

2.Use an Alloy. Many outdoor structures, like this bridge, are made from COR-TEN steel to reduce the effects of rusting
