RÉSUMÉ

A model predicting the temperature profiles of composite sprayed particles during their flight in the plasma jet is developed. Lumped thermal capacitance method is compared to full simulation taking into account the dependency of physical parameters on temperature. Coated particles composed of two materials (iron core/alumina shell) are considered for spray applications showing the influence of the possible thermal contact resistance between both materials.
