Abstract

Standing tests and after standing research of the high-temperature flame tube of the combustion chamber consisting of two-layer half-cylinders were studied, in which sheet material from chromium-based ВX-2K alloy with a protective Y—Cr—O system was used as the first wall material. It has been established that when tested according to a given program, a protective layer provides effective protection of the alloy against nitrogen saturation at high temperature.The investigated material with a protective layer maintains mechanical characterisations at a high level and virtually no significant changes compared to the original alloy.
