Abstract

A process is disclosed for phosphatizing steel, galvanized or alloy galvanized steel and/or aluminium or its alloys by treatment with a zinc phosphatizing solution applied in a dip, spray or spray/dip process. The process is characterized in that the zinc phosphatization solution has a maximum nitrate ion content of 0.5 g/l, is free of manganese, nickel and cobalt ions, contains 0.3-2 g/l zinc ions, 5-40 g/l phosphate ions and one or more accelerators.
