作者选择了一系列具有不同的正和负的曲率半径和平面试样进行渗碳,试样渗碳后进行剥层化学分析。通过一系列实验研究了试样曲率半径对碳原子渗入量(△M)、层深(d)、表面碳浓度(C_3)、碳浓度曲线上由试样表面至心部的碳浓度梯度(dc/dx)以及渗碳动力学的影响。根据这些实验数据通过教学分析得到了一系列具有较高准确度的计算参数M、J、d、C。和距表面距离为x处碳浓度C%的经验公式,此外本文还讨论了曲率半径对碳原子扩散的机制。
The authors selected a series of carburized samples with different positive and negative radii of curvature and a flat surface. The specimens were carburized and then delaminated for chemical analysis. Through a series of experiments, the effects of the curvature radius of the sample on the carbon atom penetration (ΔM), layer depth (d), surface carbon concentration (C_3) and the carbon concentration gradient from the sample surface to the heart on the carbon concentration curve / dx) and the effect of carburization kinetics. According to these experimental data, a series of calculation parameters M, J, d, C with higher accuracy are obtained through teaching analysis. And the distance from the surface at a carbon concentration of C% C empirical formula, in addition to the paper also discussed the radius of curvature of carbon atoms diffusion mechanism.
