| Abstract: | Hydrophilic groups are introduced into water based additives to improve their water solubility.The tribological behaviors of tungsten carbide (WC) coating sliding against titanium alloys under aqueous lubrication are investigated on a Timken tester. The worn surfaces of WC coating are characterized with scanning electron microscopy (SEM) and X ray photoelectron spectroscopy (XPS). It has been found that severe transfer of counterface Ti onto WC coating occurred during the lubricated sliding of WC coating against Ti alloy. The results of XPS analysis show that the interfacial layer consists of multifarious oxides, which indicates that oxidative reactions predominate the friction process under aqueous lubrication. The diffusion and adhesion wear behaviors of WC/Ti pair depend on the characteristics of the multifarious oxide layer on the worn surface of WC coating. |
