The features of the thermal regime of gas-thermal deposition 
of metal-ceramic coatings have been studied. The procedure of calculation 
of the temperature field of a multicomponent coating throughout the 
process of formation has been developed. The quantitative dependences 
of the character of heating of the deposited particles and melting 
of the substrate on the thermophysical properties and chemical composition 
of the material, the intensity of heat exchange, and the technological 
parameters of the process have been established. The thermal conditions 
of spraying of powder compositions, which ensure improved strength 
characteristics of the coating-substrate system, have been determined.
