of Al alloy using CNTs and Nb nanopowder as reinforcements and spark plasma sintering (SPS) as the fabrication method. The SPS was conducted at 630 °C, 30 MPa, 10 min, and 200 °C/min. The tribology test...%, and so was the wear rate. However, the thermal conductivity of the composite was equally improved by 44%. The tribology improvement was stimulated by a C film generated by CNTs and a protective Nb2O5......
