摘　　要：对Cr12Mo V钢采用电脉冲辅助渗硼,并对其渗硼层厚度及其性能进行了表征和分析。结果表明,电脉冲降低了渗硼温度且提高了渗硼层深度,脉冲电场的电致迁移阻碍了Fe2B向Fe B的转变,渗硼区Fe2B/Fe B相组成比例增大,耐磨性比传统渗硼提高5倍。Effective boronized thickness and properties of the Crl2MoV steel after electrical pulse （EP） boronizing were characterized and investigated. The results show that the EP can reduce the process temperature and increase the layer thickness. The electro-migration effect induced by EP inhibits the transformation from Fe2 B to FeB, the ratio of Fe2 B/FeB at the boronized zone increases accordingly; furthermore, the wear resistance of the boronized layer aided by EP is 5 times higher than that treated by the traditional boronizing process.
