The aim of the work is to improve tribological properties of an ATF oil by means of additives. Two ionic liquids (IL) and one IL with 0.1 wt.% graphene were chosen as candidates. The ILs were selected because of their promising surface interactions and proven synergy with anti‐wear additives. However, little is known about the addition of ILs to fully formulated lubricants, especially in the low temperature range. Therefore, static and sliding friction as well as wear were measured in an application‐relevant temperature range of −30 to 100°C using a rotating ball‐on‐3‐plate test. The best additive for ATF oil for material pairing 100Cr6/polyether ether ketone was 5 wt.% [P66614][TMPP][G] (halogen‐free) and for 100Cr6/sintered iron 3 wt.% [P66614][BTA]. The additives lead to a wear reduction of more than 50%. Furthermore, it could be observed that the selected ILs have different effects on the friction behaviour at the temperatures investigated.

在宽温度范围内研究有无石墨烯作为润滑剂添加剂的离子液体，用于金属/金属和金属/ PEEK触点

这项工作的目的是通过添加剂改善ATF油的摩擦学性能。选择两种离子液体（IL）和一种含0.1 wt。％石墨烯的IL作为候选物质。选择IL的原因是它们具有良好的表面相互作用以及与抗磨添加剂的协同作用。然而，对于将ILs添加到全配方润滑剂中所知甚少，尤其是在低温范围内。因此，使用旋转的3球板上测试在与应用相关的-30至100°C的温度范围内测量了静摩擦和滑动摩擦以及磨损。用于材料配对100Cr6 /聚醚醚酮的ATF油的最佳添加剂是5 wt。％[P66614] [TMPP] [G]（无卤素），用于100Cr6 /烧结铁3 wt。％的[P66614] [BTA]。添加剂可减少超过50％的磨损。此外，
