Abstract The corrosive wear performance of 304 stainless steel in sulfuric acid was determined in 1N H_2SO_4 at different polarization potentials by means of a pin-disc device. The linear relationship, with different slopes between corrosive wear and loads was confirmed. It is suggested that the removal of material in cathodic polarization region only results from mechanical wear, therefore linear relationship exists with a small sloper the synergy of corrosion and wear accelerates the removal of material in over-passive region, in which high linear slope appears; in passive region the breakdown of passive film results from shear stress, the higher of load and the more positive of potential, the more removal of material will be. So anodic protection is not suitable for corrosive wear of alloys.
