| 摘 要： | 通过对铝合金组织，化学镀镍各溶液成分，化学镀镍镀层性质，铝合金化学镀镍工艺的分析，找出了影响铝合金化学镀镍耐蚀性的关键因素是镀层厚度和孔隙率，铝合金基体状态，前处理工艺，化学镀镍工艺参数，溶液成分，镀后处理等均会影响镀层的孔隙率，所以对铝合金化学镀镍耐蚀性等级要求高的行业在使用该工艺时要控制全过程工艺要点，否则就达不到预期的目的。

| Abstract: | Through the analysis of microstructure of the hard aluminium alloy, composition of the electroless nickel plating solution, process of electroless nickel plating on aluminium alloy and properties of the nickel- phosphorus deposits, it was found that thickness and porosity of the deposit of electroless nickel plating on hard aluminium alloy were the key factors affecting the corrosion resistance of the electroless nickel coating. The aluminium alloy substrate state, pretreatment and posttreatment technologies, plating solution composition and parameters of the electroless plating process all can affect the porosity of nickel-phosphorus coating obtained. It is necessary to control correctly all important technical points in the whole process of electroless nickel plating on hard aluminium alloy for obtaining high quality nickel-phosphorus alloy coatings. |
