Mathematical Modeling of Splat Formation at Off-Normal Angles in Thermal Spray

This paper proposes a mathematical model for spatter formation at abnormal spray angles in thermal spraying. It is found that the splashes become elliptical when the spray angles are abnormal, and that the ellipse stretches the more the angle deviates from the perpendicular. The model was used to compare test results of the splash elongation at anomalous angles of impact. Paper includes a German-language abstract.
