ABSTRACT OF THE DISCLOSURE In a process of producing phosphate coatings on metal surfaces of iron or steel by a treatment with aqueous phosphating solutions on the basis of magnesium phosphate, solutions are employed which contain 0.2-to 4 g/l magnesium, 1 to 20 g/1 phosphate (calculated as P2O5) and a peroxide compound as an accelerator and are free of inorganic substances which are not precipitable with calcium hydroxide in a neutral or alkaline medium.
