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.
