6、 与 17-4PH 不锈钢配副，CrN涂层和 Cr/GLC 多层涂层的摩擦因数都显著降低。此外，涂层的磨损率分别降低了 93.1%、97.4%；对应 PEEK配副的磨损体积也分别降低了 35.1%和 65.8%。在 3 种配副条件下，PEEK 摩擦后均发生了芳香环的开放、取代、交联，以及不同程度的结晶度损失，结晶度的顺序为未磨 PEEKPEEKCr/GLCPEEKCrN PEEK17-4。结论结论 CrN 涂层的硬度、粗糙度较高，且缺少润滑，黏着磨损更显著，PEEK 材料发生了大量转移，转移材料在减轻 PEEK 磨损的同时也阻止了结晶度的降低。PEEK 与 Cr/GLC 多层涂层配副表现出最佳
7、的耐磨损性能，主要归因于摩擦时 PEEK 结晶度的维持及 GLC 中富石墨相赋予涂层的低剪切润滑作用。关键词：硬质涂层；非晶碳；石墨相；聚醚醚酮；摩擦；结晶度 中图分类号：TG115.5+8 文献标识码：A 文章编号：1001-3660(2023)06-246-10 DOI：10.16490/ki.issn.1001-3660.2023.06.021 Comparison of Tribological Behavior of Polyetheretherketone Matched with Different Hard Coatings ZHOU Xiao-hui1,2,SUN Li-li

11、n(DLC)coating is a kind of metastable material formed by the sp2 and sp3 hybrid of carbon,which has high hardness,wear resistance,chemical inertia and other properties.In particular,graphite-like carbon(GLC)coating,which is dominated by graphite-phase sp2 hybrid bond content,shows better adaptabilit

13、ith stainless steel,CrN and Cr/GLC coatings.CrN and Cr/GLC multi-layer coatings were prepared on 17-4PH stainless steel substrate(the size was 17 mm 3 mm)by multi-target magnetron sputtering deposition system.The coating thickness was about 1.8 m and 2 m,respectively.The friction testing machine was
14、 used to test the relationship between COF and time.The matching pair was PEEK ball with a diameter of 6 mm.The coating wear rate was calculated by 3D profilometer.The wear volume of three kinds of matching PEEK balls was calculated according to the volume of the crown.The physical and chemical stat
15、es of the coatings were characterized by SEM,Raman and FTIR,etc.,and the wear mechanism between the coatings and PEEK was analyzed.The results showed that both CrN and Cr/GLC multi-layer coatings could improve the friction properties when they were matched with PEEK.Compared with stainless steel,the
16、 COF of CrN and Cr/GLC coatings reduced significantly.The wear rate of CrN coating and Cr/GLC coating decreased 93.1%and 97.4%.The wear volume for counterpart PEEK decreased by 35.1%and 65.8%,respectively.The aromatic ring opening,replacement,cross-linking,and loss of crystallinity occurred in PEEK surface during sliding process,and the crystallinity was as follows:unworn PEEK PEEK grinding with Cr/GLC PEEK grinding with CrN PEEK grinding with 17-4.When PEEK was against 17-4 PH stainless steel,t
