1引言钢铁表面的彩色装饰处理，一般采用仿金电镀、化学镀铜后着色真空镀等方法。电镀法需复杂的设备和繁多工序，成本高，且镀液大多含有毒的氰化物，稳定性不好；化学镀银法一股要加热到一定温度，消耗能源，需控温设备，操作不便，镀液腐蚀性较大，稳定性差；真空镀设备复杂 1 Introduction Steel decorative color surface treatment, the general use of imitation gold plating, electroless copper plating and other methods of vacuum plating. Electroplating requires complex equipment and many processes, the cost is high, and most of the bath contains toxic cyanide, the stability is not good; chemical silver plating method to be heated to a certain temperature, energy consumption, temperature control equipment, inconvenient operation , The corrosion of plating solution is bigger, the stability is poor; vacuum plating equipment is complex
