Notes:
The quality of coatings is directly influenced by the flattening and solidification of manyindividual 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 onthe transient temperature of impacting droplets and the heat transfer between droplets and substrateplays an important role in improving the quality of coatings. Because of complexity and high cost oftemperature measurement systems for molten droplet during flattening in plasma spray forming atpresent, this paper presents a new kind of simulation measurement system for transient temperature ofspray droplets when impacting on substrate based on LabVIEW, which could display the real-timechanges of the temperature by waveform graph. Finally, the experiments were carried out on Pb-Snalloy molten droplets to reveal the close connection between the impacting droplets temperaturechanges and the coatings quality, and the heat transfer between droplets and substrate was discussed
