Effects of Elements Composition on Tribological Properties of PES/Metal Matrix Composite Materials

Abstract:

The friction and wear characteristics of PES/metal matrix composite materials were tested by the ball-disc friction pair of UMT-2 friction and wear test machine. The plastic layer is composed of distinct components. The results showed that: the tribological properties of PES/metal matrix composites were improved significantly after added 5wt % of the LCP. With the increasing of PTFE the PES/metal matrix composite material friction coefficient and wear rate were decreasing when the load of 10N and rotating speed of 400rmp. But the friction coefficient and wear rate increased when the mass fraction of PTFE more than 22 wt %. The tribological properties were the best when the PTFE content was 18 wt % to 25 wt % in the plastic layer.
