摘要	The NiAl based materials including NiAl-TiC-Al2O3 composite, NiAl-Cr(Mo)-Hf-Ho eutectic alloy and NiAl-Cr(Mo)-CrxSy in situ composite were fabricated and their wear properties were tested at different temperatures. The results revealed that the NiAl-TiC-Al2O3 composite, NiAl-Cr(Mo)-Hf-Ho eutectic alloy and NiAl-Cr(Mo)-CrxSy in situ composite exhibited the excellent wear properties between 700 degrees C and 900 degrees C. The microstructure observations exhibited that the self-lubricant films formed on the worn surfaces during the dry sliding test at high temperature, which decreased the wear rate and friction coefficient significantly. TEM observation on the self-lubricant film revealed that it was mainly comprised by ceramic amorphous and nanocrystalline. Compared with the NiAl-TiC-Al2O3 composite, the NiAl-Cr(Mo)-CrxSy in situ composite has lower friction coefficient at low temperature. Such phenomena may be ascribed to the addition of sulfide which contributes much to the formation of self-lubricant, and moreover the TiC addition increase the strength of NiAl based material and its wear resistance.
