A method for electrochemical phosphating of metal surfaces, particularly
stainless steel, in connection with cold forming of metal workpieces,
which method provides the cold formed workpiece with a lubricant after
phosphating, involves an electrochemical phosphating through a cathodic
process applying an aqueous phosphating solution containing
0.5 to 100 g Ca.sup.2+ /l
0.5 to 100 g Zn.sup.2+ /l
5 to 100 g PO.sub.4.sup.3- /l
0 to 100 g NO.sub.3.sup.- /l
0 to 100 g ClO.sub.3.sup.- /l and
0 to 50 g F.sup.- or Cl.sup.- /l
by which the temperature of the solution is between 0 and 95.degree. C.,
the pH-value of the solution is between 0.5 and 5, and the current density
is between 0.1 and 250 mA/cm.sup.2. This gives a good lubrication effect,
a good adhesion to the metal surface, particularly stainless steel, and a
more expedient texture than ordinary phosphating.
