Ti-8Si, Ti-8Si-0.7Zr, Ti-8Si-1.4Zr and Ti-8Si-1.4Zr-0.1Y2O3(wt%) alloys were preparation by high-energy ball milling, cold-pressure sintering using Ti, Si, Zr and Y2O3 powders. Morphologies and phase composition of sintered samples were analyzing by means of SEM and EDS, and the hardness, friction coefficient and wear resistance of friction/wear properties were investigated. The results show that four kinds of formula samples are mainly containing of Ti5Si3 phase, Ti(Si) solid solution and Ti(Si、Zr) solid solution. Functioned as dispersion strengthening or solid solution strengthening element, the microhardness of the formulas adding Zr and Y2O3 were improved by changing the content of Ti5Si3 and other phases and the proportion of solid solution. The formula of Ti-8Si-1.4Zr-0.1Y2O3 has the highest microhardness(1377 HV), improved by 35% than Ti-8Si(1020 HV). The friction coefficient of Ti-8Si alloy (about 0.365) was minimum, and the friction coefficient of Ti-8Si-1.4Zr-0.1Y2O3 (about 0.375) decreased by 26% than Ti-8Si-1.4Zr(0.504). Zr element decreased the wear width and improved the wear properties, while Zr element increased the friction coefficient. Ti-8Si-1.4Zr-0.1Y2O3 alloy has the best wear resistance with minimum wear width, and significantly improved the wear properties. The wear mechanism of four alloys were mainly fatigue wear, accompanied by adhesive wear, abrasive wear and oxidation wear.
