摘　　要：采用销-盘式摩擦磨损试验机研究了氧化铝增强氧化锆(ADZ)陶瓷材料/316L不锈钢摩擦副在去离子水和小牛血清2种不同介质润滑下的生物摩擦磨损行为,并利用SEM观察了磨损表面形貌。结果表明:与去离子水相比,在小牛血清润滑条件下ADZ陶瓷的摩擦因数和磨损率降低。在去离子水润滑条件下ADZ陶瓷材料的磨损为轻微磨损,相应的磨损机制为塑性变形和微犁削;而在小牛血清润滑条件下,ADZ陶瓷材料的磨损为微量磨损,磨损过程类似抛光作用。The tribological properties of alumina strengthened yttria stabilized tetragonal zirconia polycrystal ceramic （ADZ） -316L stainless steel pairs under lubrication of deionied water and bovine serum were investigated on a pin-on-disc friction and wear tester. The worn surface morphology of ADZ ceramic was analyzed with a scanning electron microscope. The results show that the friction coefficient and wear rate of ADZ ceramic under lubrication of bovine serum are lower than that of under lubrication of deionied water. The mild wear of ADZ ceramic under lubrication of deion water is related to plastic deformation with micro-ploughing, and the wear mechanism is regarded as polishing under lubrication of bovine serum.
