In fact, a range of color options can be achieved through the electroplating process. Electroplating is a way to put those little bits of copper onto something else. Zipper teeth have a complex shape, so their electroplating process is usually done in conveyor belt fashion. Note the previous paragraph, though, that everything that is somewhat reflective is not necessarily real chrome plating. Its extraction was not known and pure aluminium was extremely hard to come by. Electroplating in the Zipper Industry Zippers are usually plated with a thin coat of metal such as nickel or chromium to make them more resistant to corrosion, and to normal wear and tear. Why Is It Done? Often applied to metal pieces of machinery and mechanical parts, electroplating can be used to give metals new qualities. Why is Electroplating Done It is done because Metal has some property which the other Metal lacks Uses of Electroplating Some uses of electroplating are To prevent from Corrosion : We usually do tin coating to steel cans to prevent corrosion By giving them another electrified metal, they rush out of the solution and onto the metal’s surface. The process of depositing a thin layer of a desired metal over a metal object with the help of electric current is called electroplating. poonamdive511 poonamdive511 39 minutes ago Science Primary School Why is electroplating done?
