中文摘要:
      目的 研究渗铬界面层对铬/类石墨碳(Cr/Graphite-Like Carbon,GLC)复合涂层力学性能、结合强度及磨蚀行为的影响,阐明Cr/GLC复合涂层的抗磨蚀机理。方法 以316L不锈钢(316L)为基体,先借助双辉等离子表面合金化(DGPSA)技术制备渗铬界面层,再采用直流磁控溅射(DCMS)技术制备顶层GLC涂层。利用扫描电子显微镜(SEM)、共聚焦显微拉曼光谱仪(Raman)和X射线衍射仪(XRD)表征涂层的微结构与成分,采用纳米压痕仪、划痕仪、摩擦磨损仪和电化学工作站测试复合涂层的力学性能、断裂韧性、结合强度和抗磨蚀性能。结果 渗铬界面层能够促进GLC涂层的石墨化转变,实现硬度分布的梯度变化(基体为3.65 GPa,渗铬界面层为8.97 GPa,表面为13.15 GPa),有效阻碍了裂纹的扩展。与GLC涂层相比,Cr/GLC复合涂层具有较高的断裂韧性和结合强度(≥50 N),在3.5% NaCl溶液中具有更低的摩擦系数(0.055)和更低的磨损率(3.22×10–7 mm3/Nm),其抗腐蚀性和化学稳定性也明显更优。结论 通过界面设计,实现了Cr/GLC复合涂层硬度分布的梯度过渡,提高了复合涂层的断裂韧性以及与316L的结合强度,赋予了复合涂层优异的抗磨蚀性能,为其在海洋苛刻环境下的磨蚀防护提供了有益借鉴。
英文摘要:
      Due to its excellent chemical stability and high wear and corrosion resistance, graphite-like carbon (GLC) coating is considered as a promising tribocorrosion protective technology for metallic components under harsh marine environment. However, the inadequate adhesion strength can lead to the deposited GLC flaking or peeling off from the substrate. Because of the large mechanical and chemical mismatch between the GLC coating and the metallic substrates, such as 316L stainless steel, which may result in coating failure, especially under heavy bearing loading. Interfacial engineering is one effective strategy to solve the above-mentioned problems for GLC coating. Compared with other common physical vapor deposition methods, double glow plasma surface alloying (DGPSA) technology shows much more advantages for the preparation of buffer layer or interface layer, because its higher incident ion density benefits the formation of adhesive metallurgical layer to improve interfacial adhesion. Although much effort has been devoted to the effect of DGPSA process on the mechanical and tribological behavior of some surface modification layers, little is known about the role of Cr buffer layer prepared by DGPSA on the interfacial adhesion and tribocorrosion behavior of GLC coating. In this work, Cr interface layer was selected and introduced onto 316L substrate by DGPSA process, where the subsequent GLC coating as top layer was deposited by DC magnetron sputtering (DCMS) system. The microstructure, mechanical properties, interfacial adhesion and tribocorrosion behavior of GLC coating on the DGPSA-Cr layer were investigated. Scanning electron microscopy (SEM), confocal microscopic Raman spectrometer (Raman) and X-ray diffractometer (XRD) were used to characterize the microstructure, chemical composition and surface morphology of the coating. Scratch testing system, nano-indenter and ball on disc reciprocating friction were employed to test the interfacial adhesion strength and the mechanical and tribocorrosion properties of GLC coating, respectively. The results showed that the Cr interface layer by DGPSA method promoted the graphitization of top GLC coating. Meanwhile, even there was a great hardness difference of 14.42 GPa between GLC coating and 316L substrate, Cr/GLC composite coating exhibited the gradient transition of hardness (3.65 GPa for substrate, 8.97 GPa for Cr interface layer and 13.15 GPa for surface), which thereafter improved the bearing capacity and fracture toughness of coating. The enhanced interfacial bonding characteristics might be attributed to the synergistic effect of the formed metallurgical bonding between Cr interface layer and 316L substrate, as well as the interlocked structure between Cr interface layer and the top GLC coating. As a result, the Cr/GLC composite coating showed the higher critical load (≥50 N), low coefficient of friction (COF:0.055) and wear rate (3.22× 10–7 mm3.N–1.m–1). Specially, the wear rate of Cr/GLC composite coating was reduced by 98.27% and 46.86%, compared with those of 316L substrate and pure GLC coating without buffer layer, respectively. In addition, the Cr/GLC composite coating exhibited the excellent tribocorrosion resistance in 3.5 wt.% NaCl solution, where the graphitization transfer films were formed between Cr/GLC composite coating and Si3N4 counterpart ball. Therefore, the Cr/GLC composite coating with Cr buffer layer by DGPSA process and GLC prepared by DCMS technologies shows the excellent mechanical loading capability and tribocorrosion resistance for metallic 316L substrate, which can bring forward the promising protective coating strategy for friction components used in harsh marine environment.
