Research on Corrosion and Wear Behavior of 11Cr4NiMo Steel
As a common material for turbine blades,low-carbon martensitic stainless steel is often subjec-ted to the interaction of medium ion corrosion and mechanical wear in the service environment,and its wear mechanism still needs to be further studied.11Cr4NiMo steel was taken as the research object,the effect of microstructure on corrosion and wear behavior was studied through heat treatment regulating organ-ization structure combined with corrosion morphology,friction coefficient and wear scar morphology.The results showed that the wear mechanism of corrosion-wear was a composite wear of adhesive wear and abra-sive wear,and adhesive wear was the main wear mechanism.Among them,the wear resistance of quenched specimen was the best,the wear resistance of low temperature tempered specimen was second,and the wear resistance of high temperature tempered specimen was the worst.
