Abstract: In order to improve the wetting ability of graphene in the copper matrix, taken copper as the base and graphene as the enhancement body, add titanium carbon, and the effects of TiC on the mechanical properties of graphene/copper and its wear interface were explored.First, the Cu-TiC-graphene composite of different TiC content (0, 0.24%, 0.50%) was prepared by vacuum thermal pressure sintering(950 ℃, 20 MPa).Then the mechanical properties such as hardness and tensile strength and the friction and wear properties were studied by reciprocating wear.The results show that the addition of TiC can improve the hardness(74.2 GPa), tensile strength (47.1 MPa), reduce the coefficient of friction (< 0.2) of graphene-copper and reduce the amount of wear.
