ABSTRACT
Metallic coatings on a metal substrate are applied for several purposes, including improved appearance, improved wear resistance, influence on the solderability of materials, and corrosion resistance. The selection of the type of metal coating and the application method both depend on the properties required for the application. This chapter is primarily concerned with the application of metallic coatings for the purpose of corrosion protection. Because metallic corrosion almost always proceeds electrochemically in the material environment, the electrochemical principle of corrosion protection by coatings is discussed.
