目前低温镀铁的发展主要用于恢复尺寸,而很少用于装饰性电镀。能不能也用低温镀铁工艺代替昂贵的镀铬工艺进行装饰性电镀呢?我厂对此进行了尝试。我们采用镀铁、镍、锰三元合金,先后对178只喷油器外壳进行装饰性镀铁,镀层能够填平外壳表面的凹坑和锈蚀斑点,镀后表面光亮,效果比较满意(尚未作防蚀性试验——编者)。现将我们采用的装饰性镀铁的工艺介绍如下:
The current development of low-temperature iron plating is mainly used to restore the size, and rarely used for decorative plating. Can also use low-temperature iron plating process instead of expensive chrome plating decorative plating it? I plant this attempt. We use iron, nickel, manganese ternary alloy, has carried out on the 178 injector shell decorative iron plating, coating to fill the surface of the shell pits and rust spots, plated surface bright, the effect is more satisfactory (not yet made Corrosion resistance test - Editor). Now we use decorative iron plating process described below:
