REFRACTORY AND CERAMICS MATERIALS EFFECT OF PRODUCTION PARAMETERS ON THE STRUCTURE OF THE OUTER CERAMIC LAYER IN TWO-LAYER METAL-CERAMIC COATINGS PREPARED BY ELECTRON-BEAM DEPOSITION IN ONE PRODUCTION CYCLE

The effect of production parameters for electron-beam deposition of two-layer metal-ceramic coatings in one production cycle on the structure and phase composition of the outer ceramic layer based on zirconium oxide stabilized with yttrium oxide is studied. It is shown that it is possible to obtain metal-ceramic coatings with the required functional properties in one production cycle. [Metals: Ni, Co, Fe; substrate: gas turbine blades].
