Full TextAbstract
In this paper, a 3-D stochastic model is presented to predict the coating thickness and porosity in a thermal spray coating process. The results for different materials are obtained and compared to each other. The model is based on prescribed rules in calculating the splat size during the impact of individual droplets on the substrate. Due to thermal stresses during droplet solidification, the edge of the splats is curled up. This mechanism was assumed to be the sole reason for porosity formation. Simulations are performed for a small section of a substrate on which alumina, aluminum and nickel droplets are sprayed. The computed thickness and porosity was found to be in good agreement with those reported in the literature.
