Infrared thermography: An introductive thermal history study in aerosol deposition

Aerosol deposition (AD) system was set up, where an Infrared (IR) thermal tracer system was installed and cooperated with AD system to study the temperature variations of substrate influenced by the simulated air jet. While IR camera was focused on the surface of substrate, a live image with colorful temperature profiles was displayed, where spot reading or area averaging was made for temperature sampling. More attention was paid on thermal history of substrate surface under different conditions, in which the time dependence temperatures were collected through re-playing of image sequence file that had been continuously recorded during monitoring. AD method has been proved prospective applications in producing thin film or fine coatings to meet the fabrication requirements of miniaturized magnetic devices, piezoelectric ceramics, and high-magnetic-permeability ceramics.
