Modeling of molten droplet impingement on a non-flat surface

Numerical modeling of deformation and interaction of molten tustin, nickel and titanium droplets impinging on a rough and non-flat surface during thermal spraying has been performed in the present study. This research represents a significant advance relative to earlier published theoretical and numerical studies which were limited to a flat surface. Under the practical conditions in thermal spray processes, the complex physical phenomena of droplet spreading and consolidation take place at a microscopically rough and non-flat surface on a target substrate. The present study, therefore, provides a novel, heretofore never attempted approach to the practical impingement behavior of molten droplets. On the basis of the present study, some fundamental mechanisms governing droplet deformation on a non-flat surface may be established and the concomitant effects of important processing parameters may be determined.
