Abstract:
In the present paper, a physical engineering model is proposed to describe the process of spreading and solidification of a droplet of metallic melt containing a high volume concentration of fine solid inclusions and impacting onto a substrate. The model enables quick estimation of the final thickness and diameter of the solidified disk, or splat, formed on the substrate surface. The results obtained may prove useful for specialists in the field of thermal spraying and, in particular, plasma spraying of nano- and submicrostructured powder coatings.
