The proposed nitriding mathematical model provides a theoretical basis for solving the long-existing problems of controlled nitriding, such as slow nitriding rate, shallow effective hardening layer and poor reproducibility. On this basis, the development of a controlled nitriding electronic computer-aided design, controllable nitriding micro-computer system and micro-computer controllable nitriding process. The experimental results show that the optimal diffusion conditions of the mathematical model micro-computer controllable nitriding obvious advantages, both to improve the nitriding layer organization and performance, but also to maintain high nitriding rate, and has good reproducibility.
