| Abstract: | According to the working conditions of water hydraulic piston pump, the tribological properties of five kinds of plasma-sprayed coating against Al 2O 3 under water-lubricated condition were investigated. The friction coefficient and mass loss with time were examined. The profile and the elemental composition of the worn surfaces were observed and analyzed by scanning electron microscopy (SEM) with an energy dispersive X-ray spectrometry (EDS) attachment. The results show that the main worn mechanisms are micro cutting and fatigue fracture, affected by the water, heat, contact pressure, material transfer occurred between friction pairs. |
