The effects of electroless coatings on the microstructure and composition of the interface between multi-walled carbon nanotubes (MWCNTs) and a Cu matrix and the mechanical properties and wear behavior of the resulting copper matrix composites were investigated. Ni and Cu coatings were electrolessly plated on MWCNTs and mixed subsequently with copper powder. Then copper matrix composites were prepared by sintering, hot extrusion and cold drawing processes. The results showed that MWCNTs were straight, long, uniformly dispersed and aligned in the composites. The Ni coating is more continuous, dense and complete than a Cu coating. The tensile strength, compressive strength, microhardness and tribological properties of Ni@MWCNTs/Cu composite along the drawing direction were enhanced most. The ultimate tensile strength and compressive strength were 381 MPa and 463 MPa, respectively. The friction coefficient and wear rate were reduced by 59% and 77%, respectively, compared with pure Cu samples. This study provides a new insight into the regulation of tribological properties of composites by their interface.

Copper matrix composites with different La2O3 content were fabricated by powder metallurgy method. Sliding wear behavior of the Cu-La2O3 composites was carried out by using a pin-on-disk wear tester under dry sliding conditions at a constant sliding speed of 20 m/s. The results showed that the wear rate of the composites was significantly lower than that of pure copper. The friction coefficient and wear rate of Cu matrix composites decreased significantly by incorporation of La2O3 particles. For determination of the wear mechanisms of the composites, the worn surfaces were examined using scanning electron microscopy. It is found that the main wear mechanisms of the sintered copper-La2O3 composites were oxidation wear and adhesive wear.
