摘要 将3Y-TZP陶瓷置于常压、100℃沸水下低温老化处理0~100h,在120N载荷、0.42m/s滑行速度和蒸馏水润滑条件下对老化处理后的陶瓷进行摩擦磨损试验.结果表明:随着老化时间的延长,3Y-TZP陶瓷的硬度和抗弯强度呈下降趋势,摩擦系数经历了1个先降后升的阶段,磨损率随老化时间的延长而逐渐增大.未经老化时,3Y-TZP陶瓷的主要磨损机理为犁沟和塑性变形;50h老化后陶瓷磨损表面主要为塑性变形和微断裂;经过75h老化处理后,陶瓷的磨损率已上升到严重磨损阶段,磨损机理发生了转变;老化进行100h后,3Y-TZP陶瓷的主要磨损机理为断裂磨损. 3Y -TZP ceramic was treated under atmospheric pressure and 100℃ boiling water for 0 - 100 hours. Friction and wear properties of aged 3Y - TZP were tested under 120 N load, 0.42 m/s sliding velocity and distilled water as lubricant. The results indicated that increased aging time decreased both hardness and bending strength of 3Y -TZP ceramic. The friction coefficient of aged 3Y - TZP ceramic decreased firstly and then increased while wear rate of 3Y - TZP increased as the aging time was prolonged. The main wear mechanism of no - aged 3Y - TZP was ploughing and plastic deformation. The worn surface of 3Y - TZP ceramic after 50 h aging was controlled by plastic deformation and microfracture. A transition of wear mechanism occurred because severe wear was observed for 3Y - TZP ceramic. After 100 h aging, fracture became predominant on the worn surface.
