摘要
喷涂过程中的粒子温度与速度是影响涂层最终质量的直接因素。本文通过Al2O3-13%(w)TiO2涂层等离子喷涂工艺的正交试验,研究了电压、电流、送粉器转速和主气压强对粒子状态(温度与速度)的影响规律,并基于监测结果建立起焰流中粒子状态的表征模型,为预测粒子状态和控制涂层特征奠定基础。
For temperature and velocity of particles in plasma spraying may influence the final quality of coatings directly,through orthogonal experiment of plasma sprayed Al2O3-13%（w） TiO2 coatings,the effects of voltage,current,powder feeding speed and primary air pressure on particle states including temperature and velocity were investigated.Additionally,characterization models of particle states in plasma flame were established based on the monitoring results.These models can supply a way for forecasting particle states and thus controlling coating characteristics.
