摘要
通过建立三维温度场模型,利用数值模拟方法,模拟316L钢表面进行Ti和Al合金化的温度场分布,分析Ti、Al涂层厚度以及电子束能量密度对合金化的影响。结果表明,在能量密度为6 J/cm2电子束的一次脉冲处理下,316L钢表面合金化Ti的优化涂层厚度为1.1μm,表面合金化Al的优化涂层厚度为2μm。
Temperature field of 316 L steel substrate surface-alloyed with Ti and Al was numerically simulated through establishing a threedimensional temperature field model. Effect of Ti and Al coating thickness and beam energy density on surface alloying of the coatings was studied. The simulation results show that,under the condition of using one pulse treatment at an energy density of 6 J / cm2,the optimum coating thickness of the 316 L substrate is 1. 1 μm for the Ti surface alloying,and 2 μm for the Al surface alloying.
