摘　　要：某铝合金连接器在化学镀高磷Ni–P合金后剩磁不合格,通过分析镀层的元素组成和相结构得出是镀层中P含量分布不均所致。通过单因素试验和正交试验优化了化学镀Ni工艺,最终得到剩磁合格的产品。The remanence of an aluminum alloy connector was unqualified after electroless plating with high-phosphorus Ni-P alloy coating.It was found by analyzing the elemental composition and phase structure of the coating that the non-uniform distribution of P content in the coating was the primary cause.Products with qualified remanence were obtained by optimizing the process parameters of electroless nickel plating by single-factor experiments and orthogonal test.
