| 摘 要： | 采用M-200环-块接触型磨损实验机,分别考察了尼龙66(PA66)和SEBS-g-MA橡胶颗粒或有机纳米黏土或两者增强尼龙66在干摩擦及水润滑条件下的摩擦学性能,利用扫描电子显微镜和差示扫描量热仪对材料的磨损表面和碎片进行了观察与分析。结果表明,干摩擦条件下,PA 66+(SEBS-g-MA+organoclay)纳米复合材料的摩擦系数和磨损质量最低;当摩擦表面的温度在玻璃化转变温度T_g附近时,试样整体由于软化或者熔融而发生粘着磨损。

| Abstract: | The friction and wear behaviors of polyamide 66 (PA 66) and SEBS-g-MA rubber particles or organoclay or both reinforced PA 66 composites were investigated on an M-200 model ring-and- block contact type friction and wear tester under dry friction and water lubrication condition.In order to reveal the wear mechanisms,the worn surfaces and scraps were analyzed by scanning electron microscopy and differential scanning calorimeter.The experimental results indicat that the wear mass loss and the friction coefficient of PA 66 (SEBS-g-MA organoclay) ternary nanocomposite are the minimal compared with the other three samples.When service temperature reaches glass-transition temperature T_g,PA66 and PA66/SEBS-g-MA composite become soft,and adhesive wear is the main wear mechanism,which possibly happens under dry friction and high load conditions. |
