Wear Resistance of Ceramic Cutting Inserts Using Nitride Coatings and Microtexturing by Electrical Discharge Machining by Marina A. Volosova, Anna A. Okunkova, Elena Y. Kropotkina, Enver S. Mustafaev, Khasan I. Gkhashim

“…Today, the machining of heat-resistant alloys based on triple, quad, or penta equilibria high-entropy alloy systems of elements (ternary, quaternary, quinary iron-, titanium-, or nickel-rich alloys), including dual-phase by Gibb’s phase rule, steels of the austenite class, and nickel- and titanium-based alloys, are highly relevant for the airspace and aviation industry, especially for the production of gas turbine engines. Cutting tools in contact with those alloys should withstand intensive mechanical and thermal loads (tense state of 1.38·10⁸–1.54·10⁸ N/m², temperature up to 900–1200 °C). …”

On the formation of thermal barrier coatings by magnetron sputtering by Gennady V. Kachalin, Konstantin S. Medvedev, Aleksey F. Mednikov, Olga S. Zilova, Aleksandr B. Tkhabisimov, Dmitriy I. Ilyukhin, Vladislav A. Kasyanenko

“…The use of magnetron sputtering systems with extended uncooled targets will allow developing industrial import-substituting technologies for the formation of thermal barrier coatings, based on zirconium oxide doped with rare earth metal oxides to solve urgent problems of gas turbine construction. This paper presents the results of comparing the technology for producing thermal barrier coatings by magnetron sputtering, with two types of extended targets made of Zr–8%Y alloy – a widely used cooled target and an uncooled extended target, of a magnetron sputtering system developed by the authors. …”
