摘　　要：应用先进的Spray Watch-2i热喷涂状态监测设备,对超声速等离子喷涂过程中纳米 结构Al2O3+13％TiO2喂料的粒子温度进行了研究,优化了喷涂距离。通过监测分析,喷涂 粒子温度随喷涂距离变化曲线呈抛物线规律,在距喷嘴8-10 cm处粒子的温度达到最大。Using advanced Spraying Watch-2i thermal spray monitor, the particle temperature is investigated in the process of hypersonic plasma spraying nanostructured Al2O3-13%TiO2 feeds, and spray distance is optimized too. By graphical monitoring analysis indicates the changes of particle temperature appear parabola with the changes of spray distance and the particle＇s temperature was maximum between 8 cm and 10 cm from nozzle.
