前言采用电镀工艺方法获得的纯铁镀层,特别是采用革新后的镀铁工艺得到的镀铁层,以其特殊的物理结构及力学性能,改变了人们对采用冶炼方法所得到的工业纯铁的概念(工业纯铁的晶粒粗大,非常软,容易变形)。在国外,有的就称镀铁层为“镀硬钢”。这是有道理的。镀铁层最突出的特性就是它具有比较高的硬度。一般为H_v500左右,相当HR_c50,高的可达H_v825,相当HR_c64。而工业纯铁硬度仅为H_v88.5。即镀铁层比工业纯铁的硬度要高五至八倍,相当于优质碳钢“45钢”调质后的硬度,而耐磨性更佳,所以,它使镀铁层具有优良的耐磨损性能,因而引起了国内外材料工业的重视。例如在铸铁、普通炭钢、一般
Preface The pure iron coating obtained by the electroplating process, especially the iron-plated coating obtained by the innovative iron plating process, has changed the use of industrial pure iron obtained by the smelting method due to its special physical structure and mechanical properties Concept (industrial pure iron grain coarse, very soft, easy to deformation). In foreign countries, some call it as “hard-coated steel”. This makes sense. The most prominent feature of the iron coating is that it has a relatively high hardness. Generally H_v500 or so, quite HR_c50, high reachable H_v825, quite HR_c64. The industrial pure iron hardness H_v88.5. That is, the iron plating layer is five to eight times harder than industrial pure iron, which is equal to the hardness after quenched and tempered steel “45 steel”, and the wear resistance is better. Therefore, it has excellent iron plating resistance Wear performance, which has aroused the attention of the material industry at home and abroad. For example, cast iron, ordinary carbon steel, in general
