The work is a study of the degree of the influence of technological parameters of microplasma spraying on the coefficient of material utilization during formation of a resistive coating from titania. Investigations were conducted with application of a multifactorial experiment with fractional replicas 24–1. As a result of processing of experimental data, a regression equation was derived, which allows assessment of the degree of the influence of microplasma spraying parameters, such as current, spraying distance, plasma gas flow rate and powder consumption on the value of the material utilization coefficient. It is established that current value has the greatest influence on it. During investigations it was shown that selection of the parameters of microplasma spraying of resistive paths from TiO2 powder will allow minimizing material losses. 4 Ref., 2 Tables.
