Ti6Al4V合金在Saline溶液中的扭动微动磨损（英文）
|
摘要
在球/面接触中存在4种微动模式,即切向、径向、转动和扭动微动,在生理介质中扭动微动是人工关节失效的主要原因之一。成功建立了一种可在恒温液体介质中实现球/面接触扭动微动的新的试验系统。利用该系统,在37℃的Saline溶液中进行了钛合金/二氧化锆陶瓷球的扭动微动试验,详细讨论了扭动微动的运行行为和损伤机理。结果表明,扭动微动动力学行为在很大程度上取决于扭动角位移振幅和周期数。研究建立了扭动微动运行工况图(RCFM),包括3个区域,即:部分滑移区(PSR),混合区(MFR)和完全滑移区(SR)。在部分滑移区,接触中心没有发现任何损伤,接触边缘上只观察到轻微的擦伤和磨损。在混合区,损坏区域从接触边缘向中心扩展,接触中心无损伤,接触边缘区域出现氧化磨损和损伤。在滑移区,整个接触区域均发生损伤,损伤机理主要是磨蚀磨损、氧化磨损、和粘着磨损。
Four fretting modes exist in ball-on-flat contact according to the direction of relative motion, i.e. tangential, radial, rotational, and torsional fretting. Torsional fretting in a physiological medium is one of the main reasons for artificial joints fail. A new test system was established for torsional fretting in a liquid medium at a constant temperature in a torsional mode with a ball-on-flat contact. The torsional fretting experiments were conducted using titanium alloys/zirconium dioxide ceramic balls in a saline solution at 37 °C, and the torsional fretting running behaviors and damage mechanisms were discussed. The results show that the dynamics behaviors are strongly dependent upon the torsional angular displacement amplitude and the number of cycles. A running condition fretting map(RCFM) is established, which includes 3 fretting running regimes: a partial slip regime(PSR), a mixed fretting regime(MFR), and a slip regime(SR). No damage is observed at the contact center and only slight scratch and wear are observed on the contact edge of PSR. The damage zone extends to the contact center and the sticking zone(without damage) contracts to the contact center as the number of cycles increases, and some oxidation wear and damage occur on the contact edge of MFR. The damage mechanisms are primarily abrasive wear, oxidation wear and adhesion wear in the SR.
