How does electroplating prevent rusting

WebThe magnesium donates electrons to the iron, which slows down the rusting process. This is effective even for the parts of the iron which are not in direct contact with the magnesium. The magnesium corrodes instead of the iron, ‘sacrificing’ itself. WebElectroplating is the process of using electrodeposition to coat an object in a layer of metal (s). Engineers use controlled electrolysis to transfer the desired metal coating from an anode (a part containing the metal that will be used as the plating) to a …
