Abstract

The results of developing a (Co–Cr–Si) + (Cr–Al) diffusion coating using a two-stage powder method are presented. The mechanisms of transfer of cobalt, chromium, silicon, and aluminum atoms to the surface of a ZhS6U superalloy at the first and second stages of processing are discussed. The characteristics of the composition, structure, and life of the (Co–Cr–Si) + (Cr–Al) coating are determined at a temperature of 900°C under corrosion conditions in the presence of an aggressive salt deposit.

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.
