Abstract

The time evolution of the splat thickness, radius, and rate characteristics in the process of flattening of droplets during thermal spraying is investigated taking into account the surface roughness, splat solidification, and mass loss of the droplet liquid phase. Analytical formulas describing the final values of the splat thickness, radius, and rate characteristics are found. Results agree well with the experimental data. They can be used to predict the splat flattening parameters.
