There are many different methods of metal surface treatment. Metal surface treatment is a process where metal parts are prepared for painting. The preparation is commonly referred to as coatings pre-treatment. This usually involves creating a physical barrier that will protect metal against a corrosive environment.

The surface films used in chemical conversion coatings are formed by a means of a non-electrolytic chemical reaction that occurs between the metal surface and solution. They are adherent, inorganic crystalline or amorphous films. For the metal surface treatment to form a protective film, the base metal needs to be converted to one of the components that are less reactive to corrosion than the original metal surface.
