Abstract
In order to modify surface properties of Ti 3SiC 2, boronizing was carried out through powder pack cementation in the 1100–1400 °C temperature range. After boronizing treatment, one mixture layer, composed of TiB 2 and β-SiC, forms on the surface of Ti 3SiC 2. The growth of the coating is processed by inward diffusion of boron and obeys a linear rule. The boronizing increases the hardness of Ti 3SiC 2 from 3.7 GPa to a maximal 9.3 GPa and also significantly improves its wear resistance.
