Friction and Wear Characteristic of Electroplating Cu Coating on 0Cr18Ni9Ti Stainless Steel

摘要

In order to improve wear resistance surface on 0Crl8Ni9Ti stainless steel, Cu coating on the 0Crl8Ni9Ti stainless steel substrate was deposited by electroplating technology. The friction and wear properties of 0Crl8Ni9Ti stainless steel substrate and Cu coating were investigated contrastively. The morphologies of the wear scars were analyzed by scanning electron microscope (SEM), energy dispersive X-ray spectrometer (EDS) and scanning probe microscope (SPM), and the wear mechanism was discussed. The results showed that the wear resistance of Cu coatings was significantly improved as compared to that of 0Crl8Ni9Ti stainless steel substrate. The wear scar of 0Crl8Ni9Ti stainless steel substrate showed flaking pit, and its wear mechanism were delamination and abrasive wear. In case of Cu coating, the wear scars showed morphology of plastic deformation caused by adherent copper debris being pressed, and its wear mechanism were delamination and fatigue wear.
