摘　　要：针对环氧灌封器件表面镀层结合力差的问题,在镀前对环氧树脂灌封体进行喷砂,并将铬酸酐−硫酸体系化学粗化改为等离子粗化。采用改进的前处理工艺后,环氧树脂灌封体表面的镀层厚度、结合力及可靠性均满足宇航型号产品的使用要求。Aiming at the poor adhesion of coating electroplated on epoxy-potted components,the epoxy resin potting was treated by sandblasting,and then roughened by plasma etching instead of immersion in a bath comprising chromic acid and sulfuric acid prior to electroplating.The thickness,adhesion,and reliability of the coating electroplated on the epoxy resin potting pretreated by the said methods meet the requirements of products for aerospace applications.
