Abstract The corrosion rate, together with corrosive wear and corrosion coefficient under load, of CD--4MCu alloy in 69% H_3PO_4 or 69% H_3PO_4+500 ppm NaCl solution was measured,and the morphology of their wear tracks was then observed by SEM. The CD--4MCu alloy isrevealed to be superior in corrosive wear resistance to 304 stainless steel and even to Carpenter 20Cb_3, a high corrosion resisting alloy. From its features of duplex phase structure, it could be suggested that the weight loss related to mechanical factor was improved by existence of austenitic phase due to its deformation strengthening.
