This paper refers to the combined study of the influence of plasma flow turbulization degree on the efficiency of the plasma spraying technological process. The basis of the study is the absence of consensus between two optimization approaches, which are used to increase the profitability of plasma systems for coating, applying by the groups of scientists, who prefer laminar or turbulent plasma flow gear.The study contains: mathematical model of the heat exchange between the metal particle and plasma flow with the variation of process parameters – flow character and the dimensions of the boarder layer, which depends from the turbulization degree, controlled by the exchange of the two perpendicularly directed parts of the flow speed; laboratory performance research experiences of the plasma spraying system with the variation of the material and flow turbulization degree, which have been controlled with the help of an innovative technique. The astounding results reduce the opinions of the mainstream scientific schools into the union point, showing that the most optimal mode for the operation of plasma devices is exploitation with the flow in condition of the laminarturbulent transition
