A colored film on SUS304 stainless steel was produced by a current pulse method. Color tones were achieved by appropriate control of current cycles and the cathodic potential. The grain boundaries of the colored film were less susceptible to etching for the current pulse method as compared to other conventional approaches. The employment of current pulse tended to disperse nucleation sites with the colored film and decelerated the etching of anodic resolution in the grain boundary area. Scuffing associated with adhesive rupture and microcutting were observed in the colored film under fretting test. A microplough phenomena prevailed for the colored specimens under scratch test. Tensile cracking took place in the colored film under a scratch test with a 6.8 N constant load. The ratio of the thickness of colored films could be determined from the Auger electron spectroscopy results and from the total charges during the pulse cycles.
