Paper Title:
Microstructure and Friction and Wear Properties of the Composite Material of TiC/7075 in Powder Metallurgy
  Abstract

The research is conducted to analyze the micro structure of TiC/7075, a composite material and to study its wear properties. TiC/7075 composites produced under different sintering temperatures and with different particle contents are prepared with the help of the powder metallurgy technology. The result shows that with the increase of the TiC content, the microstructure of TiC/7075 composites tend to have the form of equiaxed crystal. The microstructure of the composite material with 8% of TiC shows the uniform and fine properties, making it have the properties of the equiaxed crystal. The hardness and the wear resistance increase with the increase of the content of TiC. Also with the increase of the sintering temperature, the sharp edge of the hole becomes smooth. The wear resistance of TiC/7075 composites is superior to 7075 matrix alloy, and the wear mechanism of TiC/7075 composites is adhesive wear and abrasive wear.
