Read More3.39.2 Zinc Phosphate Coating. Zinc phosphate coating is formed by crystallization on the surface by a chemical reaction. Zinc phosphating should be applied by spray or immersion, and it can be used for any phosphating application. Spray coating on steel surfaces ranges in weight from 1–11 g/m 2, and immersion coating from 1.6–43 g/m 2.
Read MoreCalcium phosphate forms as the result of a chemical reaction between calcium hardness (Ca) and orthophosphate (PO4). Chemically, the deposit is characterized as tricalcium phosphate (Ca3(PO4)2). The phosphate component is often contributed by a phosphate-based chemical additive, since polyphosphate is commonly used as a corrosion inhibitor.
