Phosphating Explained: How It Works and Why It Matters
Phosphating is a chemical process in which a phosphate coating is applied to a metal surface. This coating is a difficult-to-dissolve transformation layer composed of metal phosphates. It acts as a protective layer, shielding the metal from corrosion, wear, and other environmental damage.
Phosphating works through chemical reactions between the metal surface and a phosphate solution. When the metal is immersed in the solution, the phosphoric acid reacts with the metal ions to form a layer of insoluble phosphate crystals.
