Question

An iron ring is to be coated with copper. How can we do this without using
electricity ?​

Answer 1

An Iron ring can be easily coated into copper without using electricity by the process of galvanization.

• Galvanization is the method to apply a protective coating of zinc to iron and steel.

• The system stops iron and steel from rusting out. Zinc is used in the process because the zinc corrosion is very slow and increases the life of the base metal.

• A cathodic protection takes place on alloying Zinc to Iron.

• The most common method of galvinizing used is galvanizing a hot-dip, in which the pieces are immersed in a pool of molten hot zinc.
