不同构型铝基复合材料的摩擦磨损性能
Friction and Wear Properties of Aluminium Matrix Composites with Different Configurations
摘要
Abstract
Nano-SIC particle/whisker hybrid reinforced 8009Al/6061Al composites(AMC-DNC)with dual network structure were successfully prepared by spray granulation and discharge plasma sintering.At the same time,the SiC reinforced phase is uniformly distributed in 8009Al/6061Al matrix(AMC-US).In this study,the microstructure and friction and wear properties of the two composites were investigated.The friction coefficient and wear rate of AMC-DNC and AMC-US under different load and rotation speed were measured.The wear morphology was observed by scanning electron microscope,and the influence of dual network structure on the wear mechanism of composite was analyzed.The experimental results show that the density of AMC-DNC and AMC-US prepared by discharge plasma sintering method is 98.1%and 99.2%,respectively.Under low rotation load and rotation low speed conditions,the main wear mechanism of AMC-DNC is abrasive wear,in which the separation of particles leads to the rupture of oxide film,resulting in the surface damage of the material.However,under higher load and rotation speed conditions,the wear mechanism changes to peeling wear.Under the same friction and wear experimental conditions,AMC-DNC shows better friction and wear performance than AMC-US,indicating that the design of dual network stucture plays a significant role in improving the wear resistance of composite materials.关键词
