作者研究了固体润滑膜的摩擦与磨损,特别强调的是使用了内装栓-盘式摩擦试验机的扫描电镜(SEM)和能量色散X-射线分析仪研究膜的磨损率。该仪器具有半定量测量磨痕上膜厚横截面分布的优点,因而可获得膜磨损率的结果。 在5N负荷、各种气氛下,以0.3～1.0mm/s的滑动速度对溅射MoS_2膜、离子镀铅膜和溅射聚四氟乙烯(PTFE)膜进行了试验。 氧气的存在响影MoS_2膜的磨损率。MoS_2膜在氮气和真空中的磨损率比在空气和氧气中的大一个数量级。这表明,氧气的存在对降低磨损率是有益的,至少在滑动起始阶段如此。与MoS_2膜相反,铅膜在含氧气氛中迅速磨损。在所有气氛中,它们的磨损率几乎比MoS_2膜的大三个数量级。PTFE膜的磨损率几乎不受气氛的影响。
The authors studied the friction and wear of the solid lubricant film, with a particular emphasis on the use of a SEM and energy dispersive x-ray analyzer to examine the wear rate of the film using a plug-in disc friction tester. The instrument has the advantage of semi-quantitatively measuring the distribution of the cross-sectional thickness of the film on the wear scar and therefore results in a film wear rate. Sputtered MoS 2 films, ion-plated lead films and sputtered polytetrafluoroethylene (PTFE) films were tested at a sliding speed of 0.3-1.0 mm / s under a load of 5 N and various atmospheres. The presence of oxygen affects the MoS 2 film wear rate. The wear rate of MoS 2 film in nitrogen and vacuum is one order of magnitude larger than in air and oxygen. This shows that the presence of oxygen is beneficial for reducing the wear rate, at least at the initial stage of slippage. In contrast to the MoS2 film, the lead film wears rapidly in an oxygen-containing atmosphere. In all atmospheres, their wear rates are almost three orders of magnitude greater than for MoS 2 films. The wear rate of PTFE film is almost unaffected by the atmosphere.
