A Model for Rapid Solidification for Plasma Spraying

Abstract:

A two-dimensional heat transfer model, extended phase change, is developed with an enthalpy formulation in order to predict the splat/substrate thermal story and its effects on plasma surface interaction. The model validated with respect to experimental results is used to estimate the early solidification of yttria stabilized zirconia splat deposited on a cooled substrate. Simulations quantify transfers in terms of some working parameters such that the splat thickness, the splat/substrate contact quality, the latent heat of solidification and the initial temperatures.
