Abstract

PURPOSE: To improve each anticorrosive and abrasion resisting property of colored coating without using outside electric current, by carrying out coloring treatment by A solution and dipping in B solution again after giving coloring acceleration effect to stainless steel to be treated by B solution.
CONSTITUTION: Water solution containing sulfuric acid, phosphoric acid and Cr2O7 2- or that of containing sulfuric acid, Mn oxide or these salts, is made as the A solution. On the other hand, water solution adding oxalic acid to CrO water solution and regulated pH at 3W4, is made as B solution. Next, untreated stainless steel or treated by B2 pole in the bath 2 preliminary, is set at A1 pole and copper plate is set at A2 pole in the bath 1 filled up A solution. On the one hand, stainless steel treated at A1 pole preliminarily is set at B1 pole and untreated stainless steel is set at B2 pole in the bath 2 filled up B solution. Then, A1 and B2 poles, A2 and B1 poles are connected by electric conductor each other and treatment is carried out for 5W20 minutes. As a result, colored coating having each anticorrosive, heat resisting and abrasion resisting property and superior processing property, is formed on the surface of every kind of stainless steel.
