中文摘要：制备碱性镀层、酸性单层、碱酸双层，研究预镀层对锌铝合金镀镍层性能的影响。实验结果表明，碱性镀层能有效保证整个碱酸镀层的质量。试样在350 ℃下热处理1 h，然后观察试样表面形貌和界面状态，预镀层对镀层的热处理没有负面影响。
英文摘要：The alkaline pre-nickel plating, acidic nickel plating, alkaline and acidic nickel layer was prepared. The effects of pre-nickel plating on the property of electroless nickel plating were studied. The results show that the alkaline pre-nickel plating can help the whole alkaline and acidic nickel layer achieve good quality. The surface morphology and interface condition of specimen heat treated at 350 ℃ for 1 h were observed, pre-nickel plating hasn't bad effects on the heat treatment of nickel plating.
