Abstract

Abstract: Copper/graphite composites and copper/graphite/Ti2 SnC composites were fabricated through the process of ball-milling, pressing and sintering. The effects of Ti2 SnC as the second lubrication component on the mechanical properties, wear resistance and lubrication properties of copper/graphite composites were studied in this paper. The results showed that copper/graphite/Ti2 SnC composites had better hardness, impact toughness, wear resistance and lubrication performance than copper/graphite composites. The optimum values of hardness, impact toughness, friction coefficient and wear rate of copper/graphite/Ti2 SnC composites were, respectively, 56 HSD, 1.8J/cm 2, 0.15, 9.126 × 10 −6 mm 3 /N·m, while these were only 45 HSD, 1.2 J/cm 2, 0.17, 3.534 × 10 −4 mm 3 /N·m of copper/graphite composites.
