摘要

摘要介绍了使用两阶段粉末法开发 (Co-Cr-Si) + (Cr-Al) 扩散涂层的结果。讨论了钴原子、铬原子、硅原子和铝原子在第一和第二加工阶段向 ZhS6U 超合金表面转移的机制。在侵蚀性盐沉积物存在的腐蚀条件下，测定了 (Co-Cr-Si) + (Cr-Al) 涂层在 900°C 温度下的组成、结构和寿命特征。

High-Temperature Coating for Sulfide Corrosion Protection of Turbine Blades

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.
