BN/Cu复合材料摩擦磨损性能与磨损机制研究
Friction and Wear Properties and Wear Mechanism of BN/Cu Composites
摘要
Abstract
BN particles were added to BN/Cu composites during direct current assisted hot press sintering process in amounts ranging from 0.4%to 1.2%(mass fraction).The assessment of wear resistance was carried out utilizing a vertical pin-on-disc friction and wear tester,whereas the analysis of surface morphology prior to and following wear was completed employing scanning electron microscopy(SEM).Furthermore,an analysis was conducted to examine the impact of including BN particles on the physical,frictional,and wear pa-rameters of the composites.The results demonstrated that densification of greater than 96%and electrical conductivity of greater than 80%IACS were both possible in composites made by DC-assisted hot press sintering.The addition of an optimal quantity of BN parti-cles could significantly enhance the friction and wear characteristics of the composites.Due to the lubricating layer produced during the friction process,the friction coefficient of the composites was most stable when BN particles were added in an amount of 0.8%.Con-sequently,the composites exhibited outstanding friction and wear performance,primarily influenced by a combination of abrasive wear and minor adhesive wear.关键词
