| Abstract: | steady corrosive wear was employed to study corrosive wear behavior of duplex stainless steel comparing to that for austenitic and ferritic stainless steels in 69%H3PO4. The microstructures of subsurface were examined by TEM and showed that the hardness of worn surface was largely enhanced due to the high density of dislocations induced by wear surface deformation, shich were blocked by precipitation perticles in austenitic phase with low content(6.4Wt%) of nickle. It indicates that surface deformation strengthening is an effective method to improve corrosive wear resistance of alloys. |
