熔融沉积制备聚醚醚酮的生物摩擦学性能研究
Biotribological properties of polyether ether ketone prepared by melt deposition
摘要
Abstract
This study investigates the friction and wear behavior of fused deposition modeling(FDM)-fabricated poly-etheretherketone(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 analy-sis identifies fish-scale-like wear patterns.These features correlate with abrasive,fatigue,and adhesive wear mecha-nisms.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.关键词
