The corrosion rate,together with corrosive wear and corrosion coefficient under load,of alloy CD-4MCu in 69% H_3PO_4 or 69% H_3PO_4+500 ppm NaCl solution measured,and the morphology of their wear tracks was then observed by SEM.The alloy CD-4MCu is revealed to be superior in corrosive wear resistance to stainless steel 304 and even to Carpenter 20Cb3,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.
