摘要：

为了缓解我国高性能铜箔依靠进口的局面,进行了将类金属(P)和稀土金属(La)引入电解铜箔锌镍合金镀层中以获得高耐腐蚀性铜箔的实验。利用电子能谱(XPS)、X射线衍射(XRD)、扫描电子显微镜(SEM)等技术手段分析镀层质量。在最佳工艺下获得非晶态Zn-Ni-P-La合金镀层,镀层表面平整均匀、结晶致密,未钝化的情况下,铜箔镀件在180 ℃烘箱中保持1 h不变色,表现出较理想的抗氧化和抗腐蚀能力。表明镀层中适量的P和稀土La对改善镀层质量有着重要的作用,具有较好的工业应用前景。

Abstract:

In order to alleviate the situation of the country's reliance on importing high-performance copper foil, the experiment was carried out by introducing metalloid (P) and rare earth(La) in the Zn-Ni alloy coating to obtain high corrosion resistance for the copper foil. The quality of the copper foil coating was characterized by the X-ray photoelectron spectrscopy (XPS), powder X-ray diffraction (XRD) and scanning electron microscope (SEM). Zn-Ni-P-La amorphous alloy coating with well-distributed and dense crystallization was achieved by optimizing the experimental process parameters. The unpassivated copper foil can keep color for one hour in a 180 degree oven and exhibits good antioxidation and anticorrosion abilities. It indicates that a proper amount of P and La in the coating plays an important role in improving the quality of the copper foil coating, which has a good industrial application prospect.
