Abstract

Method for phosphating metal surfaces with the aid of orthophosphate solutions, characterized in that the metal surfaces are treated, without intermediate washing, with solutions of orthophosphates in two successive stages, the first stage containing wetting agents and having a ph range of 7, 1 to 7.3, while the second stage contains an aromatic nitro compound and is endowed with a ph range of 4.0 to 6.0.
