Abstract

Process for coating light metal alloy surfaces comprises cleaning the surfaces; chemically metallizing using zinc; intermediate coating in a galvanic manner; and galvanically coating using tin. <??>Preferably the cleaning step comprises degreasing the surface using an alkali, and treating the surface in an acidic solution or solution of a salt of an acid with simultaneous oxidative production of a passivating layer. Treatment with the acidic solution comprises treating in a weakly acidic solution and then in a strongly acidic solution. The weakly acidic solution contains a carboxylic acid and a pyrophosphate and the strongly acidic solution contains phosphoric acid and ammonium bifluoride.
