WebNov 14, 2015 · Galvanising is coating the iron with a layer of zinc in order to prevent it from rusting. However, sacrificial protection is attaching a piece of zinc to the iron object. Both methods use the same principle to work. Even if the iron is exposed to water or oxygen in the air, the water and oxygen react with zinc, as it is more reactive. WebZinc plating is called galvanizing (this is also sacrificial protection).

"WebZinc plating is called galvanizing (this is also sacrificial protection). Chromium plating is used on water taps and some car wheels to give a highly polished protective surface. The metal plating process (also called electroplating) uses electrolysis of a solution containing ions of the plating metal. The anode is made from the pure plating metal.
