    Abstract

    Mathematical models of computing carbon content are given in this paper. To improve the computation accuracy of carbon content, lumped parameters and mesh refinement are used in the simulation process. Finite element method (FEM) software for simulating carbon content is developed using four-node quadrilateral isoparametric elements. For a circular gear and the cylinder, FEM simulation results of carburization are contrasted with those of the experiments and the comparisons show that the simulation results are consistent with the experimental results. The carburization depth, the relationship between carburization depth and carburizing time, and the influence of the geometrical shape of the part with respect to the carbon content were studied using FEM software.
