Copper coating on Iron base metal is*0 pointsCeramic coatingAnodic coatingCathodic coatingAll
Solution
The copper coating on iron base metal is an example of a Cathodic coating.
Here's why:
In electroplating, the metal that is to be plated (in this case, iron) is made the cathode (negative electrode) in an electrolyte solution. The metal to be deposited (in this case, copper) is made the anode (positive electrode). When an electric current is passed through the solution, metal ions from the anode are reduced at the cathode, forming a coating.
So, in the case of copper coating on iron, the iron acts as the cathode and the copper acts as the anode. Therefore, it's a cathodic coating.
