Abstract

PURPOSE: To prevent sticking of smut on surfaces, make the use of resin and the like not materials contg. fluoride possible as flux and make the same safe in pollusion by performing electrolysis with an object to be plated as anode in an aqueous soln. contg. phosphoric acid then carrying out plating.
CONSTITUTION: In the case of plating other metal on iron or steel, an object to be plated as anode is electrolyzed in an aqueous soln. contg. phosphoric acid, and the smut on the surface is removed. The phosphoric acid in the aqueous soln. contg. phosphoric acid is kept at ≥50g/l and the density of electrolytic current at ≥ 1A/dm2. After such retreatment is carried out, the iron or steel is plated by an electroplating method or a hot dipping method, whereby the smooth plating layer of good adhesive strength is obtained.
