摘要: 金属的阳极钝化过程与金属所处的环境密切相关。对磁场中金属阳极伏安特性的研究表明,磁场能够明显地改变金属的钝化行为。鉴于目前这一方面的工作尚未有文献报道,本文考察了外磁场作用下铁、镍在硫酸溶液中的阳极钝化规律,并根据实验结果对钝化机理进行讨论。

Abstract: The anodic passivation behaviors of iron and nickel in sulfuric acid solution under the influence of magnetic field have been studied. The increase of passivation current density and the positive shift of passivation potential with the enhancement of magnetic field can be attributed to magneto-hydrodynamic effect and iRchange of solution respectively. The mechanism of passivation is discussed.
