摘要:

探讨了熔融沉积制备聚醚醚酮(FDM⁃PEEK)材料生理润滑环境下的摩擦磨损行为,并揭示了打印角度对其磨损量与磨损机理的影响。结果表明,200万次磨损循环周期,XY⁃0(打印角度0 °)、XY⁃30和XY⁃45的平均磨损因子分别为(5.929±1.047)×10-6、(4.702±0.989)×10-6、(4.575±0.655)×10-6 mm3/(N·m);XY水平打印的30 °和45 °样件表现出较好的耐磨性能;就磨损机理而言,不同打印角度的FDM⁃PEEK的磨损形貌基本相似;宏观上呈现表层开裂分层并伴随着弧形划痕,微观上磨损表面出现鱼鳞状磨痕,这些形貌主要与黏着磨损相关。

Abstract:

This study investigates the friction and wear behavior of fused deposition modeling (FDM)⁃fabricated polyetheretherketone (PEEK) under physiologically simulated lubrication conditions, with a focus on the influence of printing angles on wear volume and mechanisms. After 2 million wear cycles, the average wear factors for samples printed at XY⁃0 ° (0°), XY⁃30 °, and XY⁃45 ° are (5.929±1.047)×10⁻6, (4.702±0.989)×10⁻6, and (4.575±0.655)×10⁻6 mm³/(N·m), respectively. Specimens printed at horizontal angles of 30 ° and 45 ° demonstrate superior wear resistance. Regarding wear mechanisms, the surface morphology of FDM⁃PEEK remains broadly consistent across printing angles. Morphological observations revealed arc⁃shaped scratches and fracture⁃induced delamination, while morphological analysis identifies fish⁃scale⁃like wear patterns. These features correlate with abrasive, fatigue, and adhesive wear mechanisms. The findings aim to advance the application of FDM⁃PEEK technology in prosthetics design and manufacturing, offering novel strategies to support the development of personalized medical solutions.
