Abstract: Ceramic-based composites with a mixture of steel fiber and aluminium-silicate ceramic fiber were prepared by hot-pressing sintering. The effects of aluminium-silicate fiber content on friction and wear properties of the composites were discussed, and the worn surface morphology was observed by scanning electron microscopy (SEM), and wear mechanism was analyzed. The results show that friction coefficient of the composite increased with the increase of aluminium-silicate fiber contents. While the wear resistance decreased with the increase of aluminium-silicate fiber contents at high temperature. The dominant wear mechanism of the compostire without aluminium-silicate fiber was brittle spalling and fatigue wear, and accompanying with abrasive wear, while the main wear type was adhesion wear after adding aluminium-silicate fiber.
