Protective Coating for Restoring the Operability of Gas Turbine Engine Blades with Allowance for Their Service-Induced Damage

The causes of destruction of a thermal barrier coating on gas turbine engine turbine blades are studied, and the mechanism of its destruction has been revealed. A method for inhibiting the mechanism of oxide film growth at the ceramic layer–metal sublayer interface decomposition is presented. An improved metallic sublayer is proposed for the restoration of gas turbine engine turbine blades with allowance for their operational damage. The results of comparative studies of the heat resistances and thermophysical properties of various coatings are presented.

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.
