FIELD: engines and pumps. ^ SUBSTANCE: invention is related to turbine blade with coating for deterrence of Ni-based superalloy reactivity. Specified coating is made by application of material for reactivity deterrence on Ni-based superalloy surface prior to application of diffusion aluminium coating. Material for reactivity deterrence represents pure Ru, alloy Co-Ru, alloy Cr-Ru or solid solution, the main component of which is Ru, at that creation of secondary reaction zones is deterred. Turbine blades are produced with higher resistance to Ni-based superalloy oxidation by deterrence of secondary reaction zones creation. ^ EFFECT: higher resistance to Ni-based superalloy oxidation. ^ 7 cl, 4 tbl, 13 dwg, 2 ex |
