一、前言目前常用的电镀铁工艺所获镀铁层硬度高、耐磨性能好,在很多行业获得了广泛应用。这种镀铁层的组织结构,引起不少研究者的兴趣,大多数学者认为镀铁层是由α-Fe的晶态组织构成;也有一些学者认为是非晶态;还有认为是由微晶和非晶混合而成。镀铁层中的黑色条纹,大多数研究者认为是显微裂纹,有的认为是一种夹杂物,有的认为是一种镶嵌块状共沉积物。对镀铁层的强化机理也存在不同的解释。镀铁层的组织结构,决定着镀铁层的力学性能,又受约于电镀时的工艺参数。因此 I. Preface At present, the electroplated iron process commonly used by the electroplating iron layer has high hardness and good wear resistance, and has been widely used in many industries. The structure of the iron plating layer aroused the interest of many researchers. Most scholars think that the iron plating layer is composed of the crystalline structure of α-Fe; some scholars think it is amorphous; And amorphous mixture. Black streaks in the iron coating, which most researchers consider as microcracks, some as inclusions, and some as inlaid massive co-deposits. There are different explanations for the strengthening mechanism of iron plating. The structure of the iron plating layer determines the mechanical properties of the iron plating layer, but also about the process parameters of plating. therefore
