摘要

A high-temperature self-lubricating composite NiAl-Cr-Mo-CaF ₂ was fabricated using the powder metallurgy technique, and the tribological behavior of the composite at a wide range of temperatures (room temperature to 1000 °C) was investigated. The results showed that the composite had a favorable friction coefficient of about 0.2 and an excellent wear resistance of about 1 9 10 ^-5 mm ³N ^-1m ^-1 at the high temperatures tested (800 and 1000 °C). The excellent self-lubricating performance was attributed to the formation of the glaze film on the worn surface consisting mainly of CaCrO ₄ and CaMoO ₄ as high-temperature solid lubricants.
