An experimental electron-beam technology for obtaining tube billets from NiCrAlY alloys used as cathodes for the deposition of heat-resistant coatings by the ion-plasma method has been developed. It is established that coatings applied to gas turbine blades of aircraft engines using cathodes of electron beam melting meet the requirements of Motor-Sich JSC TU for this type of products.

The specifications for manufacturing of relit (WC + W2C) granular powder by the method of explosive evaporation of condensation in vacuum using electron-beam technologies are presented. It is established that when depositing material on cooled surfaces, it is possible to refine the precipitation products by metallic and non-metallic impurities, depending on the elasticity of their vapors.
