前言碳钢及低合金钢经过渗硼处理,能够获得表面硬度很高的渗层(FeB Hv1800～2000,Fe_2B Hv1200～1700),其耐磨性能,优于通常采用的渗碳、氮化、氰化、高频淬火等方法所获得的硬化层,同时,渗硼层还具有高温硬度高和良好的耐热性,以及对于某些腐蚀介质的一定的抗蚀能力。因此,近几年来,国外对于渗硼工艺给予了广泛的重视。苏、日、美、西德等国,开展了大量的研究工作,并纷纷应用于耐磨零 Preface Carbon steel and low alloy steel after boronizing, can get high surface hardness of the infiltration layer (FeB Hv1800 ~ 2000, Fe_2B Hv1200 ~ 1700), its wear resistance, better than the commonly used carburizing, nitriding, cyanide Hardening, high frequency quenching and other methods obtained hardened layer, while the boronized layer also has high temperature hardness and good heat resistance, and certain corrosion resistance for certain media. Therefore, in recent years, abroad for boronizing technology has given a wide range of attention. Su, Japan, the United States, West Germany and other countries, carried out a large number of research work, and have been applied to wear-resistant zero
