Abstract

The tribological behaviour of Ti3SiC2 containing 8% of TiC impurities, in dry-sliding, was experimentally investigated. The tests were performed on a tribometer, using corundum as a counterpart against a studied material, at room temperature with a relative humidity of 20%. The results show a decreasing friction coefficient (0.53-0.1) and an increasing wear rate (0.6–2.5)´10-6 mm3/Nm, with a sliding speed increasing from 5 to 60 m/s and under a normal pressure in the range of 0.1-0.8 MPa. The mathematical model, obtained through a modelling by design of experiment method, explains the tribological behaviour of Ti3SiC2 with curves and graphs that show the different cases of its use in industry.
