WebThe reaction between zinc oxide and phosphoric acid is exothermic and requires a strict mixing protocol to control excess heat generation. A small increment of powder is first mixed to reduce the acidity of the liquid. Subsequent increments of powder are added, and the heat also increases. WebPhosphoric acid and phosphate salts are applied and chemically reacts with the surface of the part being coated to form a porous layer. Besides steel, phosphate coatings are usually used on cadmium, silver, tin, aluminium, and zinc. The phosphate coating main types are: zinc, iron, and manganese.
