Abstract | The friction and wear of self-mated Ti3SiC2 under unlubricated condition and lubrication of PbO powders from room temperature to 700 ℃ in a nitrogen flow are studied. The results show that compared to unlubricated condition, the friction coefficient of self-mated Ti3SiC2 under lubrication of PbO powders decreases from 0.9 to 0.3–0.5 and the wear rates for pin decreases from 10_2–10_3 to 10_5–10_7 mm3/ N m. The SEM and Raman results indicate the microstructure and chemical composition of tribofilm at high temperatures have a strong effect on the friction and wear of self-mated Ti3SiC2 under lubrication of PbO powders. The composition of tribofilm varies with tribochemical and thermal reactions happening between PbO and SiO2/TiO2 on the tribosurface. The composition of tribofilms are analyzed to be PbO at room temperature, PbO and Pb3O4 at 400 ℃, and PbTiO3 and PbSiO3 at 700 ℃. The PbSiO3 is formed by tribochemical reaction while it cannot be formed under thermal condition. |
