The role of spreading during SHS surfacing of the protective coatings has been investigated theoreticaly and experimentally. The case, when spreading of large drops is forced by the effect of gravity and the interface forces are low, is considered. Analytical and numeric solutions of the problem have shown that the ratio of the specific times of cooling and spreading is the main parameter, which determines the dynamics and the final characteristics of spreading. It has been shown that the process of spreading is most strongly affected by the initial melt mass and drop size, the activation energy of viscosity, and gravitation (microgravitation and overload) within these specific times. The experimental research into SHS surfacing has confirmed the theoretical data.
