PLATED STEEL PLATE

摘要

A plated plate formed by laminating an iron oxide layer and a layer of a plating material in the mentioned order on a bare surface of steel. A joint portion comprising metal iron or an iron alloy, by which the bare surface of steel and the layer of a plating material are joined together, is provided in the iron oxide layer, whereby a layer of a plating material of a high adhesion can be formed uniformly on the whole surface of the steel plate. A method of forming a layer of a plating material of a high adhesion easily by the hot-dipping can be provided with respect to, especially, even a steel plate, which is difficult to be subjected to hot-dipping, such as a high-tension steel plate and a stainless steel plate.
