Phosphate coating process
WebThe soluble phosphate becomes insoluble in the rising pH region and phosphate coating begins to form as a result of crystallization. 3Zn +2 + 6H 2 PO 4- → Zn 3 (PO 4) 2 + 4H + + 4H 2 PO 4- This etching and coating process continues until the entire surface is covered with a phosphate layer. WebDec 13, 2024 · What is the zinc phosphate coating process? Zinc is one of the most powerful coatings available due to its ability to hold rust-preventing oils. The zinc phosphating process relies on a chemical reaction that occurs on the metal substrate when the process solution comes in contact with the metal.
