摘要
分析了ABS塑料在电镀铜/镍/铬时镀层出现起泡及结合力测试时镀层脱落的主要原因,包括塑件基体状态不良,注塑成型参数欠佳,电镀前处理不当,相邻镀层表面活性差等。给出了提高ABS塑件镀层结合力的措施,如选择优质的电镀级ABS塑料,控制成型工艺参数,改善前处理粗化及电镀工序中的活化处理等。强调了采用正确的结合力测试方法的重要性。
The main reasons for blistering of deposit during electroplating of Cu/Ni/Cr on ABS plastic and for falling-off of deposit in adhesion strength testing were analyzed, including unsatisfactory state of plastic substrate, unfavorable injection molding parameters, improper pretreatment for electroplating and insufficient surface activity of adjacent deposits. Some measures for improving the adhesion strength of electroplated coating to ABS plastic were presented, such as selecting high-quality electroplating-grade ABS plastics, controlling molding process parameters, and improving the roughening process in pretreatment as well as the activating process in electroplating. The importance of using correct method for testing adhesion strength was emphasized.
