摘要
制备新型复合润滑剂并研究其摩擦磨损特性.通过均匀设计方法优选润滑剂配方,利用SPSS软件和Matlab软件建立数学模型,并对其结果进行直观分析与回归分析.添加填充材料聚四氟乙烯制备新型复合润滑剂p2,对润滑剂的零件和模具接触面的接触摩擦状况进行分析,判断是否显著降低接触表面摩擦因数,对金属的各项性能进一步分析.研究表明,添加了聚四氟乙烯材料的润滑剂p2,相较于干摩擦与润滑剂p1,摩擦因数分别降低51.26%和29.81%;使用扫描电子显微镜观察磨痕的形貌发现,复合润滑剂在金属偶件表面形成均匀的摩擦膜,有效改善了润滑剂的性能,使成形过程中金属流动更均匀,降低了变形功及变形力,可有效避免多种成形缺陷的产生.
A new type of composite lubricant was prepared and its friction and wear characteristics were studied.The lubricant formula was optimized through the uniform design method,a model was established with SPSS and Matlab softwares,and results were analyzed by Intuitive analysis and regression analysis.The polytetrafluoroethylene(PTFE)was added to prepare a new type of composite lubricant p2,the lubricant contact friction status was analyzed to determine whether the friction coefficient of the contact surface had significantly reduced,and various properties of the metal were further analyzed.The results show that friction coefficients of lubricant p2 added with PTFE have reduced by 51.26%and 29.81%compared with dry friction and lubricant p1 respectively.Observing the morphology of the wear scars,it is found that the friction film can make the metal flow more uniform during the forming process,reduce the deformation force,and effectively avoid a variety of forming defects.
