ALLOY, PROTECTIVE LAYER FOR PROTECTION OF STRUCTURAL COMPONENT AGAINST CORROSION AND OXIDATION AT HIGH TEMPERATURES AND STRUCTURAL COMPONENT

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to protective layer, alloy from which it is implemented and structural component. Protective layer of structural component allows following composition, wt %: cobalt 11-13, chrome 20-22, aluminium 10.5-11.5, ittrium and/or at least one metal of croup, including scandium and rare earth elements, 0.3-0.5, rhenium 1.5-2.5, nickel - the rest.;EFFECT: it is received protective layer, allowing well stability against increased temperatures concerning corrosion and oxidation, well long-term stability and concordance to mechanical stresses, occurring in protected structural element.;8 cl, 6 dwg
