Abstract
A mathematical model is proposed, describing formation of a molten metal film at the tip of sprayed anode-wire under the conditions of plasma-arc spraying of coatings. Numerical analysis of the influence of spraying mode parameters on the position of molten wire tip relative to plasma jet axis, thickness of liquid interlayer contained on the wire tip, temperature and velocity of metal flow in it was performed.
