摘要
本文建立了碳扩散系数与碳浓渡有关、适用于多程快速气体渗碳的渗层碳浓度分布数学模式.利用所得数学模式,进行计算机仿真,与实验结果吻合良好.
The mathematic models of the carbon concentration profiles in the layer of multi-ple—step high rate gas carburizing of steel 20 have been established.In these modelsthe diffusion coefficient of carbon is a fuetion of carbon concentration.The computersimulating curves of carbon concentration profiles in carburized layers coincide withthe experimental results well.
