| Abstract: | Hexagonal titanium silicon carbide (Ti3SiC2) crystals were prepared by vacuum sintering of Ti, Si, and C powders at 1300 °C. The microstructure and grain deformations of Ti3SiC2 were examined by scanning electron microscopy and transmission electron microscopy. The tribological properties of hexagonal Ti3SiC2 crystals as lubrication additive in HVI500 base oil were investigated by a UMT‐2 ball‐on‐plate friction and wear tester. The Ti3SiC2 additives exhibited good friction reduction. Under determinate conditions, the friction coefficient of base oil containing Ti3SiC2 crystals is lower than that of pure base oil. The base oil with 3.0 wt.% hexagonal Ti3SiC2 crystals presented good anti‐wear capability. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
