Paper Title:
Effects of Graphite Content on Performance of Powder Injection Molding Copper-Based Antifriction Materials
  Abstract

Copper-based antifriction materials were prepared by powder injection molding. The wear rate of the antifriction material and the coupled parts, and the friction coefficient were studied under the friction condition by changing the content of graphite from 2.5 % to 25%. The results show that the wear rate and the friction coefficient decrease with the increase of the graphite content when the content of graphite is less than 10%. When the content of graphite is 10%~15%, the friction coefficient can be kept stably at low levels(0.25), thereby better density and hardness can be obtained by reducing the consumption of antifriction material and coupled parts, which improves the antifriction effect and protects the coupled parts at the same time. When the content of the graphite is larger than 15%, the wear rate of the antifriction material goes up and the friction coefficient is increased.
