中文摘要：

Tribological 特征和在 steel-to-steel 磨擦上在润滑剂油驱散的 hydroxy 镁硅酸盐(HMS ) 的自行修整的效果与各种各样的表面粗糙配对被分析。磨擦减小，反穿和各种各样的表面粗糙磨擦对的自行修整的性能被测试机器的磨擦检验。操作比较有或没有 HMS 在 SJ10W-40 润滑剂之间被做。表面形态学和磨擦裂缝的基本作文被扫描电子显微镜(SEM ) 和精力分析散分光计(版本) 。结果证明润滑油与 HMS 在润滑剂在操作以后从边界润滑油说变化进混合润滑油。磨擦减小，反穿和有各种各样的表面粗糙的磨擦对的自行修整的性能是显然不同的。有其材料与磨擦裂缝上的底层材料不同的一部修理电影。另外， Si， Mg， O，艾尔和另外的元素在包含这些元素的 nanocrystals 的修理电影上被扔。并且 HMS 自行修整的材料拥有磨擦减小，反穿和自行修整的效果的优异性能。

英文摘要：

Tribological characteristics and self-repairing effect of hydroxy-magnesium silicate （HMS） dispersed in lubricant oil on steel-to-steel friction pairs with various surface roughness were analyzed. The friction-reduction, anti-wear and self-repairing performance of various surface roughness friction pairs were examined by friction testing machine. An operation comparison was made between SJ10W-40 lubricant with and without HMS. The surface morphology and elementary composition of the grinding cracks were analyzed by scanning electron microscope （SEM） and energy dispersive spectrometer （EDS）. The.results show that the lubrication state changes from boundary lubrication into mixed lubrication after operation in lubricant with HMS. The friction-reduction, anti-wear and self-repairing performance of the friction pairs with various surface roughness are distinctly different. There is a repairing film whose material is different from substrate material on the grinding cracks. In addition, Si, Mg, O, Al and other elements are deposited on the repairing film which contains nanocrystals of these elements. And HMS self-repairing material possesses superior performance of friction-reduction, anti-wear and self-repairing effects.
