The goal of the present work is within the framework of a better comprehension of the production of a coating by plasma projection. It concerns the numerical study of the formation of splats whose stack on the substrate leading to the coating of the substrate. The application of the model, two-dimensional, uses the finite element method and the fluid volume method (VOF) to solve the governing equations, and to enable to study the impact, the spreading out and the solidification of a ceramic drop on a metal substrate and the change of the temperature of the substrate. It predicts the morphology of the slate and eventual splashes during spreading. The results were compared with the results of other authors simulations, obtained under the same conditions. Through this study, it was found that the condition and the preheating of surface play a very important rolein the morphology and formation of splats
