Sliding Tribological Behavior of Polyamide 1010 Composites Filled with ZnO Whisker

PA1010 composites filled with micrometer ZnO whiskers (ZnOw) were prepared by hot squeeze method.The nanohardness and elastic modulus of the composites were determined through nanoindentation on a triboindenter system.The sliding friction and wear behaviors were examined with a universal micro-tribometer in dry condition.The nanohardness and elastic modulus of the composites increased with the increasing content of ZnOw.The wear resistance of the composites was increased by about 60%,the friction property was maintained.The adhesion and melting were the main wear mechanism of pure PA1010,while wear mechanism of PA1010 composites shifted to fatigue rupture.
