The wear behavior of titanium silicon carbide MAX phase was investigated. Samples of highly pure Ti3SiC2 and containing 8％ of TiC, sliding dryly against Corundum counterpart, were tested at various speeds increasing from 5 to 60 m/s and under applied pressure of 0.1-0.8 MPa. The sliding-wear tests were performed on Tribometer, at room temperature of 15 ℃ with a relative humidity of 10％. The expermental results show that the presence of TiC particles can be beneficial to reducing the wear rate for certain ranges of sliding speed and applied pressure. The sliding-wear performances were expressed as a mathematical model, obtained through a modelling by the method of design of experiment. The influence of TiC impurities on the wear behaviors was also investigated. It is concluded that the wear mechanisms of samples are more affected by the presence of TiC under the effect of applied pressure compared with that of the sliding speed.
