由于渗硼层具有硬度高(HV1400～2200),耐磨性、红硬性好及在某些介质(如盐酸、硫酸及碱类等)中具有良好的耐蚀性等优良性能,因而,渗硼技术越来越受到人们的重视。但是,目前常用的渗硼工艺大都在较高的温度(850～950℃)进行,限制了渗硼技术在某些零件上的应用。为了扩大渗硼工艺的应用范围,节约能源,近来有人提出利用Crl2钢及高速钢在回火温度下渗硼,试图把渗硼温度降低到600℃以下,进行所谓“低温渗硼”。由于当前对渗硼的化学反应机理尚不十分清楚,在拟订试验方案时,在
Boronizing layer with high hardness (HV1400 ~ 2200), wear resistance, good red hardness and in some media (such as hydrochloric acid, sulfuric acid and alkali, etc.) with good corrosion resistance and other excellent performance, therefore, boronizing Technology is getting more and more attention. However, most commonly used boronization process at higher temperatures (850 ~ 950 ℃), limiting the boronizing technology in some parts of the application. In order to expand the application range of boronizing process and save energy, some people recently proposed the use of Crl2 steel and high-speed steel to infiltrate the steel at the tempering temperature and try to lower the boronizing temperature below 600 ° C for so-called “low temperature boronizing.” Due to the current mechanism of chemical reaction boronizing is not yet very clear, in the development of test programs, in
