Abstract (en)
[origin: WO2005038095A2] The invention relates to a method for phosphating metal layers by electrodeposition from acidic aqueous solutions containing at least zinc ions and phosphate ions, and by using direct current. Electrodeposition of zinc takes place in the same electrolytes and at the same time as deposition of the phosphating layer. The current density lies in the region of > A/dm<2>.
