                 Abstract: In this study, electroless plating was used to deposit a Cu layer on the surfaces of graphite and titanium silicon
                 carbide (Ti 3 SiC 2 ) particles to improve their interfacial bonding strength with the Cu matrix. Furthermore, copper-based
                 composite  materials  reinforced  with  either  copper-coated  graphite  or  copper-coated  Ti 3 SiC 2 ,  either  singly  or  in
                 combination, were prepared by ball milling, cold pressing and hot pressed sintering. The organization structure, physical
                 mechanical properties, and tribological properties of the composite materials were studied. It was found that the copper-
