摘　　要：在外加磁场中进行氮化处理,能缩短氮化时间2-3倍,能明显提高氮化层的含氮量,明显改善零件表面的机械性能。本文运用磁性理论和热力学理论对磁场在氮化过程中的影响进行较详细的理论分析。Nitride hardening in the outer electric field can shorten the time of its hardening twice or thrice, incerease its content of nitride and improve the mechanical performance of objects' surface. Here, in the light of the theories of both magnetism and heat - power, a detailed analysis on the effect of the magnetic field in the course of nitride hardening is done.
