The main types of phosphate coatings are manganese, iron, and zinc. • Manganese phosphate coatings are used both for corrosion resistance and lubricity and are applied only by immersion. • Iron phosphate coatings are typically used as a base for further coatings or painting and are applied by immersion or by spraying. WebMoreover, phosphate impedes corrosion by utilizing the promotion of highly advance defensive iron oxide films and the remedial of the flaws in protective films, respectively. Furthermore, phosphate inhibitor efficiency is abridged through chloride ions which reduces the protective film molded through the phosphate. 83
