摘要
随着工业的高速发展,人们对表面质量及性能的要求越来越高,故表面强化技术越来越受到人们的关注。等离子束表面强化技术作为材料表面热处理的重要技术手段,已广泛应用于工业生产。等离子表面强化技术是利用等离子束作为高能量热源对材料表面进行热处理的形式。结合有限元分析,通过ANSYS APDL模拟等离子束表面强化过程中的瞬态温度场变化情况,重点研究了电弧功率、扫描速度等工艺参数对其瞬态温度场变化的影响。试验结果表明,经过等离子束技术表面处理后的工件表面性能得到了明显提升。试验过程证实了等离子束表面强化的可行性及大型复杂工件的可操作性。
With the rapid development of industry,the requirement of surface quality and performance is higher and higher,so the surface strengthening technology is paid more and more attention.As an important means of material surface heat treatment,plasma beam surface strengthening technology has been widely used in industrial production.Plasma surface strengthening technology is a form of heat treatment of material surface by using plasma beam as high energy heat source.Combined with finite element analysis,ANSYS APDL was used to simulate the transient temperature field during the plasma beam surface strengthening process.The influence of process parameters such as arc power and scanning speed on the transient temperature field were studied.The experimental results show that the surface properties of the workpiece after plasma beam surface treatment have been significantly improved.The feasibility of plasma beam surface strengthening and the operability of large and complex workpieces are confirmed by the test process.
