一、专利要求 1)本专利系利用表面上锌层沉积的方法对铁表面进行镀复,其特点是:物件在镀锌之前先浸入含熔融金属或金属氢氧化物或这类混合物的浴槽中,物件处在低于锌沉积温度时便熔化,这时,浴槽对表面起到了不冒烟的熔剂的作用,而且,浸入时间足以使铁表面脱脂,且使铁物件至少预热到浴槽的熔融温度。 Patent requirements 1) The patent is the use of the surface of the zinc layer deposition method for plating the surface of the iron, which is characterized by: before the object is immersed in galvanized bath containing molten metal or metal hydroxide or a mixture of such , The object melts below the zinc deposition temperature, at which point the bath acts as a non-smoking flux on the surface and is immersed for a time sufficient to degrease the iron surface and at least to preheat the iron object to the bath’s melt temperature.
