摘　　要：采用固体粉末法对40Mn2钢进行渗硼试验,分析了稀土元素对该固体渗硼剂渗硼动力学的影响,结果表明,稀土能使硼的扩散系数增大59%,使硼的扩散激活能降低4520.31 J/mol,有效地提高了渗硼速度。Pack boronizing of 40Mn2 steel was experimentized. Effect of RE on boronizing kinetics of the pack boronizing agent was analyzed. The results showed that the RE would increase the diffusion coefficient of boron by 59% and reduce the diffusion activation energy by 4520.31 J/mol,with boronizing rate effectively increased.
