| 英文摘要 | TiC-Graphite-Ni hybrid composites integrating high hardness of TiC, lubrication of graphite and good fracture toughness of Ni, present excellent tribological properties. This paper innovatively fabricates insitu TiC-Graphite-Ni composites by pressureless reactive infiltration method, which is simple, low cost and applicable for composites with large and complex shape. The composition of composites is altered by designing C/Ti molar ratio in preforms. In-situ TiC and graphite homogeneously distribute in metal matrix with clean interface. Results show that the graphite content also affects the formation process of in-situ TiC. As C/Ti molar ratio increases from 1 to 1.5, graphite content in composites increases from 0 to 2.7 wt%, and TiC particle size reduces from 3.03 mu m to 2.58 mu m, resulting in the increase of Vickers hardness of composites from 527 to 664 HV2. With addition of TiC and graphite, tribological properties of Ni-based alloy are improved, which becomes more obvious as graphite content increases. The friction coefficient of composite with 2.7 wt% graphite is 19% lower than that of Ni-based alloy. The main wear mechanism of composites is abrasive wear. (C) 2018 Elsevier B.V.
