Phosphate Coating - an overview ScienceDirect Topics

Phosphate coatings are made up of thin crystalline layers of phosphate compounds that adhere to the surface of the metal substrate. The phosphate crystals are porous and can be formed from zinc, manganese or iron phosphate solutions. Each of the three types provides a phosphate coating with slightly different properties, such as crystal size and coating thickness.
