Abstract This work was to reveal magnetic response to wear-resistance of polyetheretherketone/Cu nanowires composites under water lubrication condition. The tribological performance, the worn surfaces, especially the tribofilms’ nanostructures and nanomechanical properties with and without magnetic field were investigated. The results reveal that magnetic field can enhance materials transfer, quicken tribofilm formation, and alleviate the stress concentration of the tribofilm. And magnetic field improves the structures and properties of the tribofilm, endowing which with superior easy-to-shear character and wear-resistance ability. Moreover, magnetic field keeps an ordering molecular structure of the PEEK matrix when transformed onto the worn surface, making up the friction heat loss due to the absorption of the running water, and further promoting the tribo-chemical reaction and the tribofilm formation.

通过对摩擦膜的磁响应提高水润滑条件下铜纳米线填充聚醚醚酮基复合材料的耐磨性

摘要 本工作旨在揭示聚醚醚酮/铜纳米线复合材料在水润滑条件下对耐磨性的磁响应。研究了摩擦学性能、磨损表面，特别是摩擦膜的纳米结构和有无磁场的纳米力学性能。结果表明，磁场可以增强材料转移，加速摩擦膜的形成，减轻摩擦膜的应力集中。磁场改善了摩擦膜的结构和性能，使其具有优异的易剪切性和耐磨性。此外，磁场在转化到磨损表面时保持 PEEK 基体的有序分子结构，弥补由于吸收流动水而产生的摩擦热损失，
