摘要

在高温条件下,奥氏体不锈钢会因严重的氧化鳞形成而遭受严重的腐蚀破坏。给不锈钢表面涂上耐腐蚀涂层可以防止过度损坏。在这种情况下,基于焊接的堆焊是一种修复受损部件的潜在方法,因为它具有更高的生产率。本研究阐述了在 AISI 316L 基板上多重堆焊 Inconel 625 (IN625) 焊层的耐腐蚀性能。通过动力学曲线研究了高温下的耐腐蚀性,进一步揭示了样品表面的腐蚀产物。分析腐蚀产物时采用了扫描电子显微镜与能量色散光谱、X 射线衍射和拉曼光谱等表征技术。熔盐环境(Na2SO4 + V2O5)下的热腐蚀动力学表明,IN625 覆盖层样品的重量增加了 40.15 毫克/平方厘米,基底的重量增加了 65.42 毫克/平方厘米。从热氧化动力学中可以看出,基底的增重是 Inconel 覆层样品的两倍多。此外,富含镍(NiO、NiCr2O4)的氧化物和尖晶石相的形成对多重叠层 IN625 试样的腐蚀动力学有很大影响。AISI 316L 基体样品显示存在临界氧化物相,如 Fe2O3 和 Cr2O3,但这些氧化物相较少,在 900°C 时不会影响耐腐蚀性。在本研究中,与 AISI 316L 相比,多重堆焊的 IN625 焊层在高温下具有优异的耐腐蚀性。

High temperature corrosion performance of Inconel 625 hard overlays deposited on stainless steel substrate

In elevated conditions, austenitic stainless steels suffer intense damage by corrosion because of the severe oxide scale development. Giving stainless steel a corrosion-resistant surface coating can prevent excessive damage. In this case, welding-based overlaying is a potential method to restore the damaged parts as it has a higher productivity rate. This investigation articulates the corrosion resistance behavior of the multiple overlapped Inconel 625 (IN625) weld overlays on the AISI 316L substrate plate. The corrosion resistance at elevated temperatures was investigated with kinetic curves, further revealing the corrosion products from the sample surface. Characterization techniques like scanning electron microscopy with energy-dispersive spectroscopy, X-ray diffraction, and Raman spectroscopy were employed to analyze the corrosion products. Hot corrosion kinetics in the molten salt environment (Na2SO4 + V2O5) revealed that the IN625 overlay samples gained a weight of 40.15 mg/cm2, and the substrate had a weight gain of 65.42 mg/cm2. From the hot oxidation kinetics, it is evident that the mass gained by the substrate is more than twice that of the Inconel overlay sample. Furthermore, the formation of oxides and spinel phases rich in nickel (NiO, NiCr2O4) highly influenced the corrosion kinetics of the multiple overlapped IN625 overlay sample. The AISI 316L substrate sample revealed the existence of critical oxide phases such as Fe2O3 and Cr2O3, which were lesser and did not influence the corrosion resistance at 900°C. In the present investigation, the multiple overlapped IN625 weld overlay offered excellent corrosion resistance at high temperature compared to the AISI 316L.
