In this study the effect of the content of [Math Processing Error] on wear properties was investigated. [Math Processing Error] composites have been fabricated by hot extrusion. Sliding wear tests were peformed by a pin-on-disk type wear test machine under dry condition and loads varied with from 20N to 80N at sliding speed 3.5Hz. The test results showed that the wear losses and the friction coefficients decreased with increasing [Math Processing Error] volume fraction and increasing the size of [Math Processing Error] particle. Wear property of [Math Processing Error] specimen was excellent all of the wear specimens. It is thought that the increase of plastic flow resistivity due to uniform distribution of [Math Processing Error] wear specimen would improve wear property. The worn surface and wear debris were examined by optical microscope and scanning electron microscope.

Keywords:composites;wear debris;pin-on-disk type wear test;frictiion coefficient
