An alternative kinetic model is suggested for analyzing the growth of iron boride layers on the surface of steel AISI 316 in the range of 1123 – 1273 K. The approach is based on classical Fick’s laws with allowance for the effect of the incubation period on the process of formation of boride layers. The activation energy of boron is calculated for FeB and Fe₂B and compared to published data. The model is verified experimentally for the case of 3-h and 5-h boriding at 1243 K. The experimental thicknesses of the layers are compared to the values predicted by the alternative diffusion model and by the integral method. The experimental and the predicted values agree well.

建议使用另一种动力学模型来分析 AISI 316 钢表面在 1123 – 1273 K 范围内硼化铁层的生长。该方法基于经典 Fick 定律，并考虑了潜伏期对过程的影响硼化物层的形成。硼的活化能是针对 FeB 和 Fe ₂ B计算的，并与公布的数据进行比较。该模型在 1243 K 下 3 小时和 5 小时硼化的情况下进行了实验验证。将层的实验厚度与替代扩散模型和积分方法预测的值进行比较。实验值和预测值吻合得很好。
