摘要
利用MM 200磨损实验机在干摩擦、水润滑和油润滑等条件下, 研究了润滑条件对含量为 10%的纳米SiO2填充尼龙 1010复合材料与 45#钢对磨时的摩擦学性能的影响, 并利用扫描电子显微镜对纳米SiO2 PA1010复合材料的磨损表面和磨损机理进行了观察和分析。结果表明水润滑时, 纳米SiO2 PA1010复合材料的摩擦因数比在干摩擦时有一定程度的降低, 但磨损量却比干摩擦时增加了很多; 而在油润滑时, 摩擦因数和磨损量均比干摩擦和水润滑时降低了许多; 复合材料的磨损机制也随着润滑条件的不同发生了相应的变化。
Effect of lubricating condition on tribological properties of 10% nano-SiO2 filled polyamide composite was studied under dry friction, water lubrication and oil lubrication on MM-200 wear tester. Scanning electronic microscope (SEM) was used to study wearing trace and wear mechanism of nano-SiO2 filled polyamide composite. The result shows that the friction coefficient of nano-SiO2 filled polyamide composite under water lubrication is less in some degree than that under dry friction, but wear loss is greatly increased, under oil lubrication, however, both friction coefficient and wear loss decrease more than under dry friction and water lubrication. The wear mechanism of composite changes under different lubricating condition.
