摘　　要：在考察了稀土化合物的摩擦学特性及其与其它白色固体润滑剂的协同关系和固－油复合效应的基础上，研制出一种白色复合固体润滑剂ＭＦＣ－１型白色润滑成膜膏．这种成膜膏具有高于７８４０Ｎ的烧结负荷，小至０．０１５的静、动摩擦因数差值，且具有抗磨、防锈和防卡咬等优良性能，已替代进口产品成功应用于国产数控机床卡盘的润滑，并为稀土开拓了新的应用领域．Normal lubricating oil and grease are not able to meet the requirements for thelubrication of mechanical equipment at high speed and heavy load . Because the black color of molybdenum disulfide or graphite is not desired for application,their range is thus limited. The tribological characteristics of rare earth compounds ,their synergistic effect with other white solid lubricants, and the combination effect of solidoil were investigated. The test results showed that MFC1 white lubricating filmforming paste has high sintering load (above 7 840 N), the difference in the value of kinetic and static friction factor was as low as 0.015. This paste exhibits good antiwear, antirust and antiseizure properties as well. It has been succes sfully used as alternative of imported counterpart for the lubrication of the clutch of numerically controlled machine tool .This has broadened the application scope of rare earth materials in tribology.
