利用超声波辅助电镀技术在AZ91D镁合金表面电镀铜.通过极化曲线、SEM、结合力测试和NaCl溶液浸泡试验,研究了超声波对镁合金电镀铜的影响.试验表明,无超声波辅助电镀所得铜层表面晶粒粗糙,结合力较差;而利用超声波辅助电镀技术所得铜层表面晶粒均匀、平整,结合力强,耐蚀性较好.SEM观察表明,超声波功率对镀层性能也有一定影响,80W超声功率下得到的镀层表面比40W超生功率的平整.
利用超聲波輔助電鍍技術在AZ91D鎂閤金錶麵電鍍銅.通過極化麯線、SEM、結閤力測試和NaCl溶液浸泡試驗,研究瞭超聲波對鎂閤金電鍍銅的影響.試驗錶明,無超聲波輔助電鍍所得銅層錶麵晶粒粗糙,結閤力較差;而利用超聲波輔助電鍍技術所得銅層錶麵晶粒均勻、平整,結閤力彊,耐蝕性較好.SEM觀察錶明,超聲波功率對鍍層性能也有一定影響,80W超聲功率下得到的鍍層錶麵比40W超生功率的平整.

The influence of ultrasonic on electroplating Cu on A291D magnesium alloy was studied by using polarization curves, SEM, adhesion test and NaCl solution immersion test. The resuks showed that the Cu deposit on A291D is rough and has poor adhesion without ultrasonic agitation. However, the Cu deposit on A291D with ultrasonic agitation has following advantages: uniform and smooth deposit grains, strong adhesion and good corrosion resistance. The power of ultrasonic has certain effect on the uniformity of Cu coating. The copper coating obtained with 80 W ultrasonic is more uniform than that obtained with 40 W.
