了解轴承中的磨损和摩擦现象对于减少摩擦和磨损至关重要。润滑油添加剂在运行过程中形成的边界层会显著影响摩擦性能。为了研究这些层的行为，使用具有不同添加剂的不同油进行了圆柱滚子推力轴承的标准化测试运行。对于这些测试，应用了用于表征滚动接触轴承润滑剂的FE-8测试装置。作为油，使用低参考值和高参考值油以及不同添加剂的油。这些油可能会在磨痕上产生不同的边界层。为了分析这些层在轴承表面上的摩擦行为，在非常低的载荷下使用微型销盘试验机。研究了100Cr 6球销在无润滑状态下与轴承盘（也称垫圈）的接触。作为对应物，轴承盘在轴承试验台中在各种油下运行后使用，未使用，并在表面上蚀刻。在施加到微型销盘测试仪上之前，去除所有粘合油。在测试期间，监测摩擦系数。测试在1 min-1的旋转速度下进行，载荷为27 mN。
Understanding the wear and friction phenomena in bearings is of key importance for the reduction of friction and wear. Boundary layers formed by oil additives during operation may significantly influence the frictional behaviour. To investigate the behaviour of such layers standardised test runs with cylindrical roller thrust bearings were conducted using differing oils with varying additivation. For these tests a FE-8 test rig for characterisation of rolling contact bearing lubricants was applied. As oil a low reverence and high reverence oil, as well as differently additivated oils were used. These oils may result in different boundary layers on the wear tracks. To analyse the frictional behaviour of these layers on the bearing surface, a micro-pin-on-disk tester was used under very low load. The contact of a spherical pin (made of 100Cr6) on a bearing disk (also called washer) without lubrication was examined. As a counterpart the bearing disks were used after the run in a bearing test rig under various oils, unused, and etched on the surface. Before application on the micro-pin-on-disk tester, all adhesive oil was removed. During the tests the coefficient of friction was monitored. The tests were performed at a rotational velocity of 1 min-1, the load was 27 mN.
