摘　　要：针对等离子喷涂工艺过程中因其复杂性和多变性导致的喷涂粉末动态行为难以直接观测的问题,本文利用Ansys软件构建了大气等离子喷涂工艺的有限元模型。模拟计算了喷涂粉末颗粒的温度场和速度场,并深入分析了喷涂距离对粉末颗粒温度和速度的影响。通过对比试验监测数据与有限元模拟结果,验证了模型的准确性。研究结果表明,最佳喷涂距离为90 mm,此时喷涂粉末颗粒的温度和速度均达到了峰值。以上研究为YSZ涂层在大气等离子喷涂工艺中的参数优化及涂层性能提升提供了理论依据与实践参考。Due to the complexity and variability of the plasma spraying process,the dynamic behaviour of the sprayed powder is difficult to be directly observed.In this paper,a finite element model of the atmospheric plasma spraying process is established using Ansys software,the temperature and velocity fields of the powder particles are simulated and calculated,and the influence of the spraying distance on the temperature and velocity state of the powder particles is deeply analysed.The accuracy of the model was verified by comparing the experimental monitoring data and the finite element simulation results.The results show that the optimum spraying distance is 90 mm,when the temperature and velocity of the sprayed powder particles reach the peak.The above study provides a theoretical basis and practical reference for the optimisation of YSZ coating parameters and the enhancement of coating performance in the atmospheric plasma spraying process.
