Abstract
Mathematical model has been developed, describing turbulent flow of the electric arc plasma and formation of the plasma jet under conditions of plasma-arc spraying. Detailed analysis of the effect of working parameters of a plasmatron using an anode wire and conditions of blowing about a low-turbulent plasma jet it generates with a laminar gas flow on electric parameters of the arc discharge, thermal and gas-dynamic properties of the plasma flow has been conducted on the basis of numerical modelling.
Keywords: electric arc spraying, wire material, arc plasmatron, mathematical model, software, characteristics of plasma flow
