1.          Electrorating

Electroplating bụ usoro nke na-emepụta ihe mkpuchi metal dị mkpa n'elu ala site na electrolysis.Ihe eji eme ihe na-arụ ọrụ dị ka cathode, na ihe mkpuchi dị ka anode na usoro.A na-eji ihe ngwọta nke acid, bases, ma ọ bụ nnu mee ihe iji duzie ihe dị ugbu a.N'ebe a, ihe mkpuchi ahụ kwesịrị ịdị na ngwọta mmiri.

Ion ihe mkpuchi ahụ na-aga na cathode ka a na-etinye ọkụ eletrik na electrodes, ebe ha na-edobe oyi akwa.A na-ejikarị usoro a eme ihe nana-etinye Zincna ihe ferrous.
