摘要

A model of the metal droplet evaporation in non-equilibrium arc plasma is proposed, which predicts a nonstationary mode of droplet heating in the case where ionization of the vapor cloud evaporating from the droplet gives rise to a further increase in the evaporation rate. This mode is shown to occur for a great variety of substances and is most conspicuous when evaporation of a material is accompanied by high-intensity thermionic emission from the droplet surface.
