摘要(Abstract)：

采用4种不同施镀工艺在51CrV4蝶形弹簧表面制备了4种镀锌层,采用目测法观察镀层的外观及镀层覆盖完整情况,采用硫酸铜试验测试分析镀层厚度的均匀性,采用划格试验法测试镀层的结合强度。结果表明:保持性活化剂+沉积性活化剂施镀和复合活化剂施镀制备的镀层均存在一定缺陷,工件表面有漏镀、镀层不完整,并且镀后蝶形弹簧边缘镀层容易脱落。通过硫酸铜置换铜层后,使得基体表面的成分改变,不易析出杂质,保持洁净,改善了锌粉颗粒在基体表面的沉积效率以及镀层与基体之间的结合强度,减少了漏镀和镀层脱落,获得了覆盖更为完整、厚度均匀的镀层,镀层的耐腐蚀性得到提高。对闪铜后施镀的两种镀层进行对比,复合活化剂施镀镀层粗糙,但结合相对较好,施镀过程也更简便。对基体经硫酸铜置换铜层后再进行施镀所得的两种镀层进行比较
