采用一种改进的销盘试验来确定典型刹车片成分的摩擦学性能。这些成分与氧化铁和石墨一起球磨提供了显示真实第三体主要特征的模型材料。固体润滑剂（如石墨）对Fe3O4粉末的摩擦磨损行为有很大影响，而进一步添加硬质纳米颗粒只会产生微小的影响。与模型结果的比较证实了这一点。二硫化钼起到了双重作用。根据特殊情况，这种成分可以减少或增加摩擦。经过纳米表征后，后者可以通过氧化和破坏耐磨摩擦膜来解释。(C) 2014 Elsevier Ltd.版权所有。
A modified pin-on-disc test was applied to determine tribological properties of typical brake pad constituents. Ball-milling of these ingredients together with iron oxide and graphite provided model materials displaying the main features of real third bodies. Solid lubricants like graphite affected the friction and wear behaviour of Fe3O4 powders considerably whereas further addition of hard nanopartides induced only minor effects. This was corroborated by comparison with modelling results. MoS2 played a dual role. Depending on special conditions, this ingredient either reduced or increased friction. The latter could be explained, after nanoscopic characterization, by oxidation and destruction of the wear-protecting tribofilm. (C) 2014 Elsevier Ltd. All rights reserved.
