摘要: 用失重法、动电位阳极极化、XRD、SEM 及EPMA 等多种实验方法研究了四种硅含量对不锈钢在高温浓硫酸中的腐蚀行为, 结果表明:高硅的加入使不锈钢的耐酸性能显著提高。 认为其主要原因是硅的加入促进了不锈钢的纯化, 并使其表面形成外层以SiO^2、内层以Cr^2O^3为主的纯化膜。
英文摘要: The influence of silicon contents on the corrosion behaviors of stainless steel in highly concentrated sulfuric acid was investigated by the methods of weight loss, potentiodynamic anodic polarization, X ray diffraction (XRD), SEM, EPMA and auger electron spectroscopy (AES). The results indicated that adding high silicon content into stainless steel improved the corrosion resistance significantly in highly concentrated sulfuric acid because of the accelerated passivating process and the formation of SiO^2 in outer layer and Cr^2O^3 in inner layer.
