Beschreibung
Zusammenfassung:	FIELD: structural members for hot gas passages, turbine blades, heat shields, etc containing metal base made from nickel-, cobalt- or iron-based super-alloy. SUBSTANCE: adhesion enhancing layer is also used for forming aluminum oxide/chromium oxide. Heat-insulating layer consists of trioxide or pseudo-trioxide with structure of pyro-chlorine or perovskite which are phase-stable between room temperature and melting temperature. Besides that, article may be used for manufacture of elements by plasma spraying or PVD. EFFECT: enhanced stability to hot gases. 22 cl, 5 dwg
