| 摘 要： | 以纳米MgO/SiO2作为添加剂,在HQ-1摩擦磨损实验机上进行自修复实验。试验考察载荷、转速、修复时间对纳米MgO/SiO2复合添加剂自修复性能的影响。实验结果表明,纳米MgO/SiO2在适宜的条件下对钢-钢摩擦副磨损金属表面有修复效果,其修复性能受载荷、转速及修复时间等条件影响;纳米MgO/SiO2添加剂对磨痕具有一定的填平作用,在一定程度上能够改善磨痕的粗糙度。

| Abstract: | In order to study the influence of load,slide velocity and restoration time on automatic restoration capability of composite nanometer MgO/SiO2 additive that added to 350SN lubricating oil.Systematic wear tests and automatic restoration tests were done on HQ-1 wear machine.The results show that composite nanometer MgO/SiO2 has obvious effect of repairing on steel friction pairs under certain friction conditions,its automatic restoration capability is affected by load,slide velocity and restoration time.Composite nanometer MgO/SiO2 can improve the frictional surface and reduces the surface roughness of friction pairs. |
