摘　　要：利用复合电镀方法制备Cu-纳米AlN复合涂层。利用金相显微镜和SEM观察,结果显示镀层表面形成了厚度为40μm左右的均匀复合镀层,XRD测试表明该合金镀层为Cu和AlN,采用浸泡腐蚀失重法和测定极化曲线比较了纯铜镀层和复合镀层的耐腐蚀性能,结果表明:Cu-纳米AlN复合涂层耐蚀性优于纯铜镀层。Cu-nano AlN composite plating were co-deposited by composite electroplating method.The Optical microscope and SEM observation showed that an intermetallic compound layer was formed uniformly on Cu surface and its thickness was about 40 μm.The XRD analysis indicated that the coating was mainly consisted of Cu and AlN.The corrosion resistence was investgated by acetate immersion and electrode potential and polarization curves.The result indicated that the Cu-nano AlN coating have better corrosion ressistance than coating of Cu.
