【Abstract】 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.更多还原
