Abstract

Procedure for phosphating-passivating metals, characterized in that the metal is brought into contact with an aqueous solution of phosphating-passivating, which contains an acidic phosphate component, an acidifying agent and, possibly, a surfactant and/or an accelerator oxidizing agent, the acidifying agent comprises at least one organic polyacid chosen from oxalic acid and hydroxypolyacids and this agent is present in an amount such that the pH of the aqueous solution is between approximately 3 and 6.
