Aluminium naturally forms a thin surface layer of aluminium oxide on contact with oxygen in the atmosphere through a process called oxidation, which creates a physical barrier to corrosion or further oxidation in many environments. Some aluminium alloys, however, do not form the oxide layer well, and thus are not protected against corrosion. There are methods to enhance the formation of t… WebOnce again, the passivation treatment refers to removing that surface iron with an acid solution. In this case, the other components of the alloy are left behind as a surface layer over the underlying steel, and upon exposure to air they react with oxygen to form the passive metal oxide layer that protects the rest of the steel from corrosion.

WebChem film, also called chemical film, is a chemical conversion coating. It typically refers to a chromate conversion coating applied to aluminum and its alloys. The chemfilm coating provides a layer of corrosion protection and a base for paint and primer. When applied as a thin coat, chem film can allow for electrical conductivity.
