High-Temperature Seals for a Gas Turbine Stator

Abstract

Sealing assemblies and welded rings made of nickel superalloys for sealing the gas–air path of the stator in a gas turbine engine are developed. Samples of sealing assemblies and cross-sectional profiles of U- and W-shaped sealing rings made of KhN50VMTYuB alloy tapes are demonstrated. Key quality requirements for sealing elements are formulated.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
