铝及铝合金光亮化学镀镍的研究

摘要

研究了一种新的、简便的、环保的铝及铝合金化学镀镍新工艺，探讨了前处理、光亮剂添加量对镀层质量的影响。结果表明，铝及铝合金经过自制浸锌剂二次浸锌后，每升镀液中添加15mL光亮剂所获得的样品镀层均匀、结合力最佳。%This research studies a new simple environment-friendly aluminum and aluminum alloy eleetroless nickel plating process, analyses the influence ofpretreatment and bright plating additives on deposit quality as well. The experimental results show that an optimal deposit with even coating and strong binding force was achieved after two-time zinc dipping with self-made zinc dipping agent and 15ml brightener in every
