1Relationship between wear behaviour of ultra-high-molecular-weight polyethylene and surface profile of Co–Cr–Mo alloy in artificial joint显示文摘The relationship between the wear behaviour of an ultra-high-molecular-weight polyethylene(GUR1050)pin and surface profile of a Co-28Cr-6Mo alloy(ASTM F-75)disc was investigated.Tribological tests have been performed by pin-on-disc wear testing machine with multi-directional pathways,obtaining the influence of micro slurry-jet erosion(MSE)processed Co–Cr–Mo alloy.The specific wear and the wear particles have been investigated.It was elucidated that the Co–Cr–Mo alloy surface processed by MSE influenced the specific wear rate of polyethylene;however,the morphological aspect of polyethylene wear particles was not drastically changed.The wear particles isolated from the lubricating liquid were added to a culture medium,and human monocyte-derived macrophages were incubated by using an upright/inverted method.The production of TNF-α and IL-6 seemed to have a correlation with the amount of wear particles added,however,the influence of particle size on the production of TNF-α and IL-6 was not obvious.This means that the improvements for the incubation method,i.e.upright/inverted method,need further investigation for the accurate analysis.Nana Motojima Yuta Nakashima Yukio Fujiwara Yoshihiro Komohara Motohiro Takeya Hiromasa Miura Kazunori Hino Hidehiko Higaki Hidehiro Hata Yoshitaka Nakanishi 2019Biosurface and Biotribology2019,5,1:0
