| 目的 对比聚醚醚酮(PEEK)与不锈钢、CrN涂层、Cr/GLC多层涂层3种配副的大气环境摩擦学行为。方法 采用多靶磁控溅射镀膜技术在17–4PH不锈钢基底表面制备CrN涂层和Cr/GLC多层涂层。采用摩擦磨损试验机和三维轮廓仪对配副摩擦因数和磨损率进行测试，采用扫描电镜、拉曼光谱仪和显微红外光谱仪等方法，表征不同配副摩擦前后的表面物理化学状态，剖析涂层与PEEK配副的磨损机理。结果 CrN涂层和Cr/GLC多层涂层均显著提高了不锈钢基底的摩擦性能，相较于PEEK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PEEK>PEEK–Cr/GLC>PEEK–CrN> PEEK–17-4。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。 |

| The surface coating technology can improve the friction and wear behavior of the substrate while maintaining its excellent mechanical properties. CrN coating as the representative of hard coating materials with high hardness can effectively resist impact and abrasive wear, and is often used in mechanical bearing shaft, piston pin and other friction protection. Diamond like carbon (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 adaptability to multiple environments. In order to carry out the technical optimization of polyetheretherketone (PEEK) matching materials, and solve the problem of easy wear of PEEK material of PEEK-stainless steel friction system, the work aims to compare and investigate the tribological behavior of PEEK matched with 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 ϕ17 mm ×3 mm) by multi-target magnetron sputtering deposition system. The coating thickness was about 1.8 μm and 2 μm, respectively. The friction testing machine was 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 states 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 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, the micro-convex of the substrate spalled and hard particles were formed, resulting in abrasive wear. Part of the PEEK transferred to the substrate surface and another part of the formation of wear debris piled up on the edge of the grinding crack, caused by wear sharp PEEK surface crystallinity slash and mechanics performance, eventually leading to the decrease of the material abrasion resistance. When PEEK is matched with CrN coating, because the CrN coating surface is rough and lack of lubrication, it can plough the PEEK surface, which makes the adhesive wear more significant. A large amount of PEEK material transfer occurs and the transfer material can reduce PEEK wear and prevent the decrease of crystallinity. When PEEK is matched with Cr/GLC coating, it is attributed to the good crystallinity stability of PEEK and excellent lubrication of graphite structure in Cr/GLC multi-layer coating. |
