要約

This paper presents a numerical study of transient heat transfer and phase change of a thermal spray coating problem. The early solidification of yttria stabilized zirconia splat deposited on a cooled substrate is considered. These phenomena are quantified 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. 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 results are in good agreement with an experimental one for the case of a nickel splatting on an alumina substrate.
