Abstract

Process for phosphating surfaces of metal objects, especially those of aluminum, zinc and iron, characterized in that the metal surface is coated, at temperatures between 20 and 35º c, with a solution of zinc-manganese phosphate, in the presence, in the solution, of an accelerator and of copper ions, the latter in an amount between 0.1 and 30 mg/1, the phosphating being carried out under conditions such that the degree of free acidity of the solution is from 0.1 to 0.5 approximately.
