The problem of poor adhesion of electroplated ruthenium coating to the molybdenum slice was solved by a two-step pre-plating method.The process mainly includes degreasing,anodic etching,alkaline cleaning,slight etching,bright dipping,pre-immersing,chromium pre-plating,nickel pre-plating and ruthenium plating.The process removes the high temperature annealing,lowering the energy consumption.The electroplated ruthenium topcoat is firmly adhered to the molybdenum slice substrate.%采用两步预镀的方式解决了钼片与镀钌层之间的结合力差的问题.主要工艺流程包括除油、阳极浸蚀、碱洗、弱浸蚀、出光、预浸、预镀铬、预镀镍和镀钌.采用此工艺省去了高温退火,能耗低,所得钌面层与钼片基体结合牢固.
