Superhard Coatings on the Basis of High-Entropy Alloys

Section: Scientific and Technical Innovative Projects of National Academy of Sciences of Ukraine
Language: Russian
Abstract: The technology and properties of new class of superhard coatings based on high-entropy alloys and developed by the authors is presented. High-entropy alloys — a new class of materials, are used as starting material for deposition. Application of the improved technological modes of vacuumarc deposition allowed on the basis of solid soluble high-entropy alloys to obtain superhard coatings with thermal stability up to 1100 °С.
Key words: high-entropy alloys, nitride coatings, dimpling, hardness, module of resiliency, thermostability.
