摘要

In this article, the trajectories of ceramic and metal particles in plasma spray are calculated by solving related momentum and energy equations. Meanwhile, the spatial distributions, temperatures, velocities, as well as diameters of the particles are measured by employing an online, in-flight particle sensor (DPV2000). The experimental and computational results are in good agreement. It has been found that the particle flying trajectories are dependent on material types and particle diameters, and in a plane vertical to the spraying axis, there is a certain corresponding relationship between the particle diameter and the particle velocity, as well as particle temperature.
