摘　　要：采用显微组织观察（OM）和x射线衍射（XRD）等研究了电脉冲频率对Crl2MoV钢固体渗硼工艺的影响。结果表明，电脉冲辅助Crl2MoV钢固体渗硼可以有效提高其渗硼层和过渡区厚度。当脉冲频率为9Hz时，Cr12MoV钢的渗硼层厚度达到53μm，是传统渗硼工艺的2．65倍，且过渡区厚度达到145μm，是传统渗硼工艺的2．07倍。Effect of pulse frequency on boronizing process of Crl2MoV steel was researched by OM and XRD. The results show that the thickness of boride layer and transition layer of Crl2MoV steel can be improved by EPT-aiding. The maximum thickness of boride layer reaches 53 μm, which is 1.65 times higher than than of the traditional boronizing process, and the thickness of transition layer reaches 145 μm, which is 1.07 times higher than than of traditional boronizing process, when the pulse frequency is 9 Hz.
