Abstract

The dependence of the coefficient of use of ceramic powder material on the parameters of coating by the plasma spraying method was obtained in the work. The dependences of the material utilization factor and arc current, the ratio of argon and nitrogen consumption, the total consumption of plasma gases, the spraying distance and the fractional composition of the powder material are established, and the natural limitations of the variability of these parameters are described. The dependence of the material utilization factor on the average value of the fraction range has been established.
