研究了丁腈橡胶（NBR）的微动磨损行为。详细讨论了微动运行行为、摩擦系数和磨损机理随位移幅值和载荷的变化规律。结果表明，磨损表面的粘着层在微动磨损中起着重要作用。在不同的微动运行状态下，材料会表现出不同的损伤特征，微动特征与位移幅值有很强的相关性。而法向载荷对微动磨损的演变影响不大。X射线光电子能谱（XPS）的结果表明，在微动试验过程中，橡胶没有发生热降解。(C)2015爱思唯尔有限公司版权所有。
The fretting wear behavior of acrylonitrile-butadiene rubber (NBR) was studied. The variation of fretting running behavior, coefficient of friction (COF) and wear mechanisms as a function of displacement amplitude and load were discussed in detail. Results showed that the sticky layers on the worn surface played an important role in fretting wear. Various damage characteristics could be exhibited in different fretting running regimes, and the fretting characteristics were strongly dependent on the displacement amplitude. However, the normal load had little effect on the evolution of the fretting wear. The results of X-ray photoelectron spectroscopy (XPS) revealed that no thermal degradation occurred in rubber during fretting tests. (C) 2015 Elsevier Ltd. All rights reserved.
