当您初次见到这个名词,可能感到很陌生。其实,这是在我国流传了千百年的一项传统金属强化工艺,在手工作坊中广泛使用着。简单说,就是在熟铁或低碳钢锻坯上,擦上或淋上一薄层生铁,再经多次冷锤,成型后淬火,使工件的一面渗碳,并有生铁熔覆层,使表面强化,因而工件既耐磨又锋利。它是锻造、铸造与热处理三结合的复合金属工艺,在今天的农具手工业中用在入土农具上。它的起源很早,公元四世纪南北朝时期,当时不可能获得液态钢,我们的前辈能工 When you first see this term, you may feel strange. In fact, this is a traditional metal strengthening process that has been circulating in our country for thousands of years and is widely used in hand workshops. In short, that is, in the wrought iron or low carbon steel forging blank, rub or cast a thin layer of pig iron, and then after several cold hammer, quenching after forming, so that one side of the workpiece carburizing, and pig iron cladding, So that the surface hardening, so the workpiece is both wear-resistant and sharp. It is forged, cast and heat treatment of three composite metal technology, used in today’s farm tools hand tools on the soil tools. It originated very early, during the Northern and Southern Dynasties in the fourth century AD, it was impossible to obtain liquid steel at that time, and our predecessors could work
