本研究旨在比较聚醚醚酮（PEEK）聚合物基体中固体润滑剂在不同接触压力和滑动速度下的摩擦学行为。从摩擦学的角度来看，PEEK在无润滑滑动时具有较高的摩擦系数，但磨损率非常低。虽然，当一些纤维增强剂和润滑剂添加到聚合物基体时，摩擦系数显着降低，但磨损行为是不确定的。从摩擦学测试来看，聚醚醚酮聚合物基体在表面形成转移膜，影响磨损率。建立了基于量纲分析的数学模型，以确定对转移聚合物薄膜形成的影响。这是根据操作条件、成分和粗糙度来定义的。(C) 2016 Elsevier Ltd.版权所有。
This study is aimed to compare the tribological behaviour of solid lubricants in a polyetheretherketone (PEEK) polymer matrix under different contact pressures and sliding speeds on dry reciprocating conditions. PEEK from the tribological viewpoint presents relatively high friction coefficients during unlubricated sliding but the wear rates are remarkably low. Although, when some fibres reinforcement and lubricants are added to this polymer matrix the coefficient of friction reduces significantly but the wear behaviour is indeterminate. From tribological tests, PEEK polymer matrix generates a transfer film in the countersurface which influences wear rate. A mathematical model based on dimensional analysis was performed to determine the influence on transfer polymer film formation. This was defined in terms of operating conditions, compositions and roughness. (C) 2016 Elsevier Ltd. All rights reserved.
