Being extremely soft coatings, chromates are very easy to scratch when they are wet. As the coating becomes dry, it becomes hard and more abrasion resistant. It has an additional value as a primer for organic coatings, as metals like aluminum are generally difficult to paint or glue. Chromated parts retain their electrical conductivity to varying degrees, depending on coating thickness. The process may be used to add color for decorative or identification purposes also. Darker coatings generally provide more corrosion resistance. The chromate film protects the plated metal by acting as a barrier against corrosive atmospheres. The more hexavalent chromium trapped in film, the higher will be the coloration and will in turn, offer better corrosion resistance.
