The quality of coatings is directly influenced by the flattening and solidification of many individual molten droplets in plasma spray forming, so many properties such as thermal, electrical, mechanical etc are strongly linked to the real contact between the “piled-up” splats. The research on the transient temperature of impacting droplets and the heat transfer between droplets and substrate plays an important role in improving the quality of coatings. Because of complexity and high cost of temperature measurement systems for molten droplet during flattening in plasma spray forming at present, this paper presents a new kind of simulation measurement system for transient temperature of spray droplets when impacting on substrate based on LabVIEW, which could display the real-time changes of the temperature by waveform graph. Finally, the experiments were carried out on Pb-Sn alloy molten droplets to reveal the close connection between the impacting droplets temperature changes and the coatings quality, and the heat transfer between droplets and substrate was discussed.
