Abstract

In this study, Cr₃C₂/10%NiCr layer was deposited on the AISI 2205 duplex stainless steel by the HVOF technique. Microstructural, tribological and corrosion behaviors of the coated and uncoated samples were investigated. The characterization studies were carried out by scanning electron microscopy, energy dispersive spectroscopy and optical microscopy. Moreover, dry sliding wear tests, corrosion tests and hardness measurements were performed to reveal the influence of Cr₃C₂-10%NiCr on the properties of AISI 2205 duplex stainless steel. Microstructural analysis revealed that proper bonding was achieved at the substrate-coating interface. On the other hand, it was observed that the coating structure consisted of chromium carbides and nickel-chromium binders. According to the corrosion test results, it was observed that the coating protected its structure and delayed the corrosion damage of the AISI 2205 alloy. The wear rate of the AISI 2205 alloy was reduced from 73.32 ± 5.28 × 10⁻⁵ mm³·(Nmm)⁻¹ to 6.97 ± 0.61 × 10⁻⁵ mm³·(Nmm)⁻¹ with Cr₃C₂-10%NiCr coating, as a result of the wear tests. In conclusion, test results showed that the Cr₃C₂-NiCr layer improved the corrosion and wear behavior of the AISI 2205 duplex stainless steel.

高速富氧喷涂 Cr3C2-NiCr 涂层对 AISI 2205 的腐蚀和磨损性能的影响

本研究采用HVOF技术在AISI 2205双相不锈钢表面沉积Cr3C2/10%NiCr层。研究了涂层和未涂层样品的显微组织、摩擦学和腐蚀行为。采用扫描电子显微镜、能量色散光谱和光学显微镜对其进行表征。通过干滑动磨损试验、腐蚀试验和硬度测试，揭示了Cr3C2-10%NiCr对AISI 2205双相不锈钢性能的影响。显微组织分析表明，在基材-涂层界面处实现了良好的结合。另一方面，涂层结构由碳化铬和镍铬结合剂组成。腐蚀试验结果表明，涂层保护了AISI 2205合金的组织，延缓了合金的腐蚀损伤。Cr3C2-10%NiCr涂层使AISI 2205合金的磨损率从73.32±5.28 × 10−5 mm3·(Nmm)−1降低到6.97±0.61 × 10−5 mm3·(Nmm)−1。综上所述，Cr3C2-NiCr层改善了AISI 2205双相不锈钢的腐蚀磨损性能。

期刊介绍： ASM International''s Journal of Materials Engineering and Performance focuses on solving day-to-day engineering challenges, particularly those involving components for larger systems. The journal presents a clear understanding of relationships between materials selection, processing, applications and performance. The Journal of Materials Engineering covers all aspects of materials selection, design, processing, characterization and evaluation, including how to improve materials properties through processes and process control of casting, forming, heat treating, surface modification and coating, and fabrication. Testing and characterization (including mechanical and physical tests, NDE, metallography, failure analysis, corrosion resistance, chemical analysis, surface characterization, and microanalysis of surfaces, features and fractures), and industrial performance measurement are also covered
