When aluminum and aluminum alloys are immersed in a controlled chromic acid bath with additives, a chemical conversion reaction takes place at the surface of the metal. This reaction produces a complex , non-crystalline, non-porous coating consisting of a thin aluminum oxide film with entrapped chromates and dichromates. The corrosion resistant properties of the coating are primarily due to the chromates, specifically the hexavalent chromium.
Various chemical activators are used to enhance the formation of the coating. Depending upon the desired performance characteristics of the chromate film, the chromating bath is often modified by changing these activators.
