In this paper, theoretical and experimental studies of the kinetics of the spreading of liquid drops of molten metal over a solid metal surface in the absence of extraneous (external) driving forces of hydrostatic pressure, gravity, etc. In the kinetic mode, wetting appears as the spreading of liquids on a solid surface. Wetting and spreading are spontaneous processes occurring due to a decrease in the surface energy of the Gibbs system
