摘要
在盘销摩擦磨损试验机上研究了不同用量、粒径的硅灰石填充的双马来酰亚胺复合材料与硬铝的滑动摩擦磨损性能．借助于扫描电镜分析，探讨了硅灰石调节双马来酰亚胺摩擦学性能的作用机理．结果表明：随硅灰石的用量增加、粒径减小，双马来酰亚胺和铝环的耐磨性提高，滑动摩擦系数减小；硅灰石提高滑动副的耐磨性是因为硅灰石促进了双马来酰亚胺在铝 环表面形成牢固的转移膜．
The sliding friction and wear properties of bismaleimide filled with different amount and size of wollastonite were studied against hard Al on a pin-on disc tribometer. The mechanisms that wollastonite adjust the tribology properties of BMI were analyzed by means of SEM. It has been showed that wollastonite can raise the wear resistance of BMI and reduce its sliding frictional coefficient with the increase of amount and decrease of size of wollastonite. The reasons of wollastonite increasing wearability are that wollastonite promotes BMI to form firm transfer film on the Al surface.
