摘要: 研究了6Crl3不锈钢经磷酸溶液短时处理后耐蚀性的变化以及磷酸浓度、外加铜离子对耐蚀性能的影响。使用AES和XPS技术分析了6Crl3钢经这种处理后表面膜的化学组成和结构。结果表明,6Crl3钢经处理后耐蚀性的提高与表面膜内铬的富集有关,其表面膜的组成和结构则与磷酸溶液的浓度有关。

Abstract：Corrosion resistance of 6Cr13 stainless steel after short time treatment in H_3PO_4 solutions was evaluated in 3.5% NaCl at 25℃ for 4 hrs and the effect of H_3PO_4 concentration in and the addition of Cu~(2+) to the solutions on corrosion resistance were also studied AES and XPS were employed to determine the chemical composition and structure of the surface films formed on the steel. The results indicated that the increase in corrosion resistance of the treated steel was related to the enrichment of Cr in the surface films. The structure of the surface films was dependent upon H_3PO_4 concentration in solutions.
