摘　　要：根据齿轮的二段渗碳工艺建立了渗碳过程的有限元数学模型,结合具体的渗碳工艺条件,编制计算程序,进行了模拟分析,得出了渗碳过程的碳浓度分布;重点分析了渗碳过程齿轮表面及内部碳浓度的变化特点,在强渗期和扩散期内渗碳层深度的变化规律,并对渗碳层碳浓度分布的模拟结果进行了试验验证。Based on FEM mathematical models to describe the carburization process and practical carburization technical conditions, two - step gear carburization is simulated by programming, from which the carbon content distribution in carburization process is obtained. Carbon content changes in the gear surface and interior is analyzed, the principles of carburization depth changes in the intensive earburization and diffusion stages is analyzed. The simulation result is verified by later experiments.
