Abstract (en)
Surfaces of iron-based metals or zinc-based metals are phosphated by contacting the metal surfaces with an acidic aqueous solution containing from 0.1 to 2.0 g/l of zinc ion, from 5 to 30 g/l of phosphate ion, from 0.2 to 3 g/l of manganese ion, and a conversion coating accelerator. The phosphated metal surfaces are then suitable for electrocoating.
