    • Abstract
  • First Cu-Cr alloy powders were prepared by alloying method,and then nano-AlN particles strengthened graphite/Cu-0.6%Cr composites were gained by adding of 10% graphite particles and different content of AlN particles into the Cu-Cr alloy.The influence of nano-AlN content on the density,conductivity,hardness,bending strength,wear and friction properties of the composites was studied.The results show that with the increase of nano-AlN content,the hardness and bending strength increased,the density,conductivity and wear mass loss decreased,and friction coefficient changed little.When the nano-AlN content was 0.5%,the bending strength and wear resisting property of the composite could be improved effectively in the premise of not reducing the electrical conductivity too much.
