The coating material is injected into a very high temperature plasma flame (up to 10,000 K in heat), it is rapidly heated and then accelerated to a high velocity onto the surface of the part and rapidly cools to form a coating on the parts surface. (eds.) While zinc is frequently the metal of choice to provide corrosion protection, a zinc-nickel alloy such as the one offered by Sharretts Plating Company tends to produce better long-term results than when coating with zinc alone. 101110. It is pliant and can be soldered almost as well as tin. Recent Advances in the Science and Technology of Materials 3, pp. Mater. 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 cathode (the part to be plated). When the electricity flows through the circuit the electrolyte splits some of the metal atoms from the anode, which are then deposited in a thin layer on top of one of the cathode. In: Perea, A., Montero Ruiz, I., Garcia-Vuelta, O. Rhodium plating, cadmium plating and tin plating are also kinds of metal plating used for both decorative purposes and corrosion resistance. Iron and steel commonly plated with chromium. The driving power for pitting corrosion is the depassivation of a small area, which becomes anodic (oxidation reaction) while an unknown but potentially vast area becomes cathodic (reduction reaction), leading to very localized galvanic corrosion. Its corrosion resistance is one of the main benefits of hard chrome plating, because it helps extend the life of metal parts that get exposed to air and moisture. Metal plating can be done either by electroplating or an electroless plating process. In: Barral, P., Dedet, B., Delrieu, F., Giraud, P., Le Goff, I., Marion, S., Villard-Le-Tiec, A.
