The Wear Mechanisms Transition Map of Plasma Sprayed Al2 O3-13 wt.% TiO2 Coating under Dry Sliding
等离子喷涂Al2O3-13wt.%TiO2涂层在干摩擦条件下的磨损机制转变图

The wear behavior of plasma sprayed Al2O3-13wt.% TiO2 coating against WC hard alloy has been investigated within a load range of 10 to 100 N and a sliding speed range of 0.1 to 0.5m/s under dry sliding.Through careful analysis of the worn surface of the coating,the wear mechanisms transition map of this coating has been established.As the result,the main wear mechanism of the coating is plastic deformation and microploug at low normal load and low sliding speed,that is,within the wear rate range of 0.1 to 1...
