Abstract

Procedure for the phosphating-passivation of metals, characterized in that it comprises bringing the metal into contact with an aqueous solution of phosphating-passivation that contains an acidic phosphate component, an acidifying agent and, possibly, a surface-active agent and/or an accelerator. oxidizing agent, the acidifying agent comprises sulfamic acid and this agent is present in an amount such that the pH of the aqueous solution is between approximately 3 and 6.
