Short answer: Phosphating immerses steel (or zinc/galvanised surfaces) in a phosphate bath that grows a crystalline, micro-porous conversion layer — zinc phosphate as the primer key for paint and powder coating, iron phosphate for light wear and lubrication, and manganese phosphate for heavy-duty break-in and corrosion resistance. The coating is non-dimensional, conductive and oil-absorbing, making it the standard pre-treatment under paint, a running-in film for gears and bearings, and a corrosion barrier for fasteners and tubes.
