摘要
为了探讨离子渗金属过程中碳迁移的定量规律,通过对离子渗金属过程中扩散过程的分析,给出了合金渗层和脱碳层深度以及合金元素和碳元素分布的有限差分解法,并根据一组实验参数进行了数值计算和实验验证.结果表明,渗层深度和合金元素分布以及脱碳层深度和碳元素分布的计算值与实验结果吻合较好,渗层深度的误差在5%以内,总脱碳层深度的误差在10%以内.
In order to discuss the problem of definite quantity of the carbon migration in plasma surface alloying process,the diffusion of alloy and carbon element was analyzed.The solutions to the difference equation were supplied on the depth of the alloying layer,the decarburized layer,the distribution of alloy elements and carbon in the layer.The numerical calculation and the experimentation were accomplished with certain technical parameters.The results show that the numerical value of calculation is consistent ...
