Investigation on microstructure and wear behavior of the NiAl-TiC-Al2O3 composite fabricated by self-propagation high-temperature synthesis with extrusion

► NiAl-TiC-Al2O3 composite sliding wear at high temperature. ► The wear debris is oxidized and compacted on the surfaces of the composite and SiC. ► The lubricant film forms on surfaces of composite and friction pair. ► The friction coefficient and wear rate decrease and stabilize at low level.
