一、前言 十九世纪六十年末,用电解法获得化学纯铁,从而产生直流电镀铁技术,但它作为一项修复或表面强化手段,最早是由苏联学者[Ⅰ]在本世纪四十年代首先提出,并广泛用于汽车、拖拉机等零件的修复。等人还用镀铁技术对普通低碳钢零件进行表面强化处理,以代替某些优质合金钢。本世纪七十年代以来,美、日等国家也开始广泛研究这一技术问题,出现了一些镀铁工艺及应用的专利和文献。并很快形成很大的
I. Introduction By the end of the sixtieth century, chemical pure iron was electrochemically obtained to produce DC electroplating iron technology. However, it was first used as a repair or surface strengthening method by Soviet scholars [1] in the 1940s First proposed, and is widely used in automobiles, tractors and other parts of the repair. And others also use the iron plating technology on the surface of ordinary mild steel parts to strengthen treatment to replace some high-quality alloy steel. Since the seventies of this century, the United States, Japan and other countries have also begun extensive study of this technical issue, there have been some iron plating process and application of patents and literature. And quickly formed a great deal
