摘要： 研究了TZP陶瓷在固体润滑下，室温（25℃）至600℃制备范围内的摩擦学特性．结果表明，使用石墨和MoS2润滑剂，可在室温至600℃范围内降低TZP／Si3N4摩擦副的摩擦系数和磨损率，但当环境温度过高时，摩擦系数和磨损量有所增加；使用CeO2和Cu对TZP／Si3N4摩擦副的摩擦系数影响不大，但可以降低TZP陶瓷的磨损量；CeF3在高温时，由于结晶化趋势完善及沿（002）面的滑移取向，故可对TZP陶瓷起到良好的润滑作用．

Abstract: The tribological properties of TZP ceramics under solid lubrication up to 600℃ were investigated. Using either graphite or MoS2 can reduce the friction coefficient and wear rate of
TZP/Si3N4 sliding couple from 25 to 600℃, however, their lubricating characteristics can be deteriorated due to the oxidation of these lubricants over excessive high temperature. Using CeO2
and Cu can reduce the wear rate of TZP ceramics, but they don’t have apparently influence on the friction coeffcient. CeF3 has good lubricating properties at high temperature, which is due to its completed crystallization and orientation alone (002) plane.

Key words: TZP ceramics, friction, wear, lubrication
