Metal anodes are pieces of metals that are used in electrochemical processes like electroplating or corrosion protection. Many different metals are used such as aluminum, zinc, magnesium, titanium, tin, cadmium, lead, copper, or various alloys such as bronze and brass. Different metals are chosen as anodes for various reasons. For example, some metals are more ductile than others are while some have superior strength.
There are two types of metal anodes. Sacrificial anodes are used for corrosion protection. These anodes are chosen because the metal of the anode is more easily corroded than what you are trying to protect. Electrons that are removed from the sacrificial anode are transferred to the protected metal so that it becomes a cathode. The extra electrons allow reduction to occur on the surface of the protected metal rather than corrosion.
Plating anodes are used mainly for plating and electroplating applications. Plating is done for several reasons including for aesthetic reasons, for corrosion protection, to harden, to improve paint or coating adhesion, for radiation shielding, or many others. Electroplating is a special process for plating that uses electrical current to facilitate the coating process.
