用加速化学和电化学腐蚀实验(LSV)研究了一系列有机缓蚀剂在镍镀层表面形成的配合物膜的耐蚀性,结果表明,肉豆寇酸在镍镀层表面形成的膜耐蚀效果最佳。采用XPS和AES研究了配合物膜层的结构与性能,以及在金属表面的成键特征和波谱变化,探讨了配合物膜的组成、性能、结构、化学状态和形成机理。配合物膜由镍的氧化物和镍的肉豆寇酸配合物组成,其中Ni和O分别呈+2、+3和-2价。 Accelerated chemical and electrochemical corrosion experiments (LSV) were used to study the corrosion resistance of a series of organic corrosion inhibitors on the surface of the nickel coating. The results showed that the corrosion resistance of the film formed by myristic acid on the surface of the nickel coating optimal. The structure and properties of the complex films were studied by XPS and AES, as well as the bonding characteristics and spectral changes on the metal surface. The composition, properties, structure, chemical state and formation mechanism of the complex films were discussed. The complex membrane consists of a nickel oxide and a nickel myristate complex, with Ni and O at +2, +3 and -2 valences, respectively.
