    Abstract

    The diffusion profile of dinitrotoluene deterred nitrocellulose based small arms propellants is investigated with Confocal Raman microscopy. The diffusion profile in all samples was found to be non-Fickian Case II diffusion - a steady concentration with a sharp drop. Diffusion depth from the outside surface was found to be much greater than the interior perforation surface. A strong correlation was found between the perforation size of samples and their inside edge diffusion depth, while the outside surface was found to be more dependent on total diameter and deterrent concentration. Samples were also artificially aged to investigate movement of the deterrent over time.
