Application of cobalt-based alloys of Co–Cr–Si–B system for protective coatings
https://doi.org/10.22349/1994-6716-2019-97-1-39-43
Abstract
The paper studies an alloy of Co–Cr–Si–B system for obtaining powder materials and functional coatings based on it. It is shown that nanocrystalline precipitates are formed and increase substantially the microhardness of the coating when rare-earth elements, namely yttrium, lanthanum, and cerium, are introduced into the alloy.
Supporting agencies: Experimental studies were performed on the equipment of the laboratory of the Test and Technical Complex of Irradiated and Radionuclide Materials and the Center for Collective Use “Composition, Structure and Properties of Structural and Functional Materials” of the NRC “Kurchatov Institute” – CRISM “Prometey”.
