Effect of a moving flame on the temperature of polymer coatings and substrates
Flame spraying has substantial advantages over liquid paint and electrostatic spraying but the process is thermally complex due to the moving flame-spray gun over the substrate. This paper quantifies how the scanning action of the flame affects the temperature profiles within the polymer and shows how overheating of its surface can be avoided. This contributes towards enabling the possibility of developing a new flame-spray process as a replacement for painting (liquid and electrostatic with a total worldwide market of £70 billion) in certain specific applications.
