Abstract
The dry sliding behaviors of titanium silicon carbide (Ti3SiC2) against Ni–Cr and Ni–Cr–Ti alloys from ambient temperature up to 600 °C were investigated. The tribological performance of Ti3SiC2 depends largely on counterface materials. Fracture and pullout of Ti3SiC2 grains followed by mechanical mix led to poor tribological property for Ti3SiC2/Ni–Cr alloy tribo-pair. However, for Ti3SiC2/Ni–Cr–Ti alloy tribo-pair, the oxides film of Ti on Ni–Cr–Ti alloy was effective to reduce friction coefficient and enhance wear resistance.
