Question

to prevent rusting ,a layer of metal is applied on iron sheets

Answer 1

The unsightly orangy-brown mess that accumulates on metal is a highly unattractive feature that plagues many different objects, especially cars, trucks, screws, bolts, and tools. Under the appropriate conditions, rust may strike rather quickly or take its time slowly eroding your belongings. When oxygen and moisture come into contact with exposed metal, rust is unfortunately the result. While the corrosion is removable in most cases, it is much better to prevent rust rather than deal with its aftermath. A layer of steel can be applied on Iron to prevent rusting

Answer 2

heya dude...
here is ur answer.......!

yes,, the metal used to coating is more reactive than iron, so it oxidises in preference to the iron object. the active metal such as zinc. Zn loses in preference to iron and prevents the rusting of iron. The process by which iron is protected by Zinc is called galvanization.
