Phosphating is a chemical conversion treatment that produces an insoluble phosphate crystal layer on metal surfaces. It enhances corrosion resistance, improves paint adhesion, and adds lubricity. Common in automotive, machinery, appliances, and military applications, it serves as an essential base for further surface coatings.
