| Abstract | The tribological behavior of self-mated Ti3SiC2 in low viscosity fluids, that is, water and ethanol, is investigated. The results show that both water and ethanol effectively reduce the friction and wear of self-mated Ti3SiC2. The friction coefficient and total wear rates of Ti3SiC2 tribo-pair are 0.82 and 2.17×10-2 mm3/N m under dry condition, 0.41 and 6.50×10-4 mm3/N m in water and 0.16 and 2.22×10-4 mm3/N m in ethanol. As sliding distance is prolonged from 0.5 to 22.9 km, the total wear rates of Ti3SiC2 in ethanol can be further reduced. Mechanical wear of Ti3SiC2 is partly inhibited in water and greatly inhibited in ethanol. Surface polishing of Ti3SiC2 pin and tribochemistry are the two distinct characteristics of self-mated Ti3SiC2 in ethanol. The surface film in ethanol is composed of TiO2 and SiO. Tribo-products in ethanol, that is, silica gel and titanium dioxide, are found. Polycondensation of ethanol by the catalysis of TiO2 and SiO2-x gives birth to paraffins and olefins. |
