As its name suggests, corrosion resistant coating is applied to protect the substrates from the chemical or electrochemical attacks from the environment, which would otherwise cause various types of corrosion. The choice of coating depends on the type of material the substrate is made and the type of corrosion prevention needed. Chromium, copper, nickel and zinc are among the most widely used coating materials.
Anodising is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. This is especially effective to protect aluminum although it is also possible for titanium, zinc, magnesium etc.
