摘要

It is of great significance to find ways to control the high-temperature friction and wear of ceramic materials. In this paper, a ZrO ₂ matrix high temperature self-lubricating composite with addition of MoS ₂ and CaF ₂ as lubricants were prepared using hot pressing method by tailoring the composition of CaF ₂. The wear and friction behavior of the composites was investigated from room temperature to 1000°C. The ZrO ₂-MoS ₂-CaF ₂ composites against SiC ceramic exhibited excellent self-lubricating and anti-wear properties at a wide temperature range. At 1000°C, the ZrO ₂-10MoS ₂-10CaF ₂ (wt.%) composite has a very low coefficient of friction of about 0.27 and wear rate of 1.54×10 ^-5mm ³/(Nm). The low friction and wear were attributed to a new lubricant CaMoO ₄ which formed on the worn surfaces at high temperatures.
