Abstract : To protect surface of substrate from heat loss, a Thermal insulation layers(TIL) were produced by the supersonic
spraying process which is consisted of a supersonic nozzle, an atomizer, a gas heater, a syringe pump, and a x-y motor stage.
While it has been found that sufficiently thick coating layers improve thermal protection, still we want to manufacture
thinner layer using optimal coating materials; clays, silica, and aerogels have been used, and have the properties which are
non-toxic, competitive price as cheap in this research. Herein, we show the high-performance results using thermal coating
layers regard to insulation of both heat and cooling. The thickness of layers is from 1 to 5 mm, Aerogel/SiO2/Mont. 3 mm
layer performed best insulation effect about 100 °C comparing to bare case. Deposition by supersonic cold spraying are rapid
and scalable to large area, so do applicable for commercial industry.
