Investigation of the formation of complex surface layers with elevated characteristics, which contain Cr, Ti, Zr, HF, and, Si, B, C, Mo using vacuum activated diffuse saturation and gas phase deposition (CVD) on steels, refractory metals and carbon materials for use in space technology, aviation and nuclear industry, mechanical engineering popup.stage_title Head Rudenky Sergii G., Доктор технічних наукStolbovyi Viacheslav O., Registration Date 25-01-2022 Organization National Science Center "Kharkiv Institute of Physics and Technology" popup.description2 The purpose of the research is to develop protective coatings to ensure the possibility of products functioning at elevated temperatures and the effect of destructive effort. Stage 1 is the development of processes of multilayer nitride or carbonitride coatings formation with tungsten nanolayers and the study of structural transformations, properties and treatment of such coatings under different types of physico-mechanical processing. The research object is vacuum-arc multi-layer coatings WN/Me (Me = Zr, Cr, Mo, Nb). Phase analysis of coatings was carried out using the X-ray diffraction of Bregga-Brentano (XRD, X-ray diffractometer Panalytical Empyrean) with the radiation of Cu-Kα (λ = 1.5406 Å). To measure residual stresses, method 2θ-Ω was used in the drop configuration with the radiation of Co-Kα (λ = 1.78901 Å) at U = 40 kV and I = 30 mA. The morphology and cross-section of multilayer coatings WN/Me (Me = Cr, Zr, Mo, Nb) were studied using a high resolution scanning electron microscope (FE-SEM) JEOL JSM 7600F. The total thickness of multilayer coatings was measured using a calotester (Anton Paar Compact CAT2c Calotester). The relief and roughness of the surface were determined using Zeiss LSM 700 according to ISO 25178. The crystallographic characteristic of the WN/Nb multi-layer coatings was determined using the electron microscope in a bright field mode (BF), translucent electron microscopy of high resolution (HRTEM) in the high-thief mode of a dark field (HAADF). For nanoscale multilayer coatings WN/Me (Me = Cr, Zr, Mo, Nb) applied by the vacuum arc method, the microstructures, mechanical properties, friction and wear resistance characteristics were conducted.   Product Description popup.authors Serchenko Maryna P Solovichenko Yuriy M Ilchenko Nora S Andreev Anatoly O Barankov Mikhail Ya Bredikhin Mikhail Yu Getman Valentyna F Dolomanov Andrey V Zmij Victor I Kartsev Mykola F Kovalenko Volodymyr I Kovteba Dmytro V Konovalov Igor I Korneev Olexander O Kryvoshapka Ruslan V Kunchenko Olexij V Kunchenko Yuriy V Lytvyak Alina K Lukirsky Yuri V Lyashenko Igor A Marynin Volodymyr H Martynenko Lyudmyla I Myroshnychenko Kostjantyn V Pavlenko Volodymyr I Rak Vasyl' I Ryzhova Tеtyana P Rudenky Sergey H Serdyuk Iryna V Stolbovoy Vyacheslav O Chernoivanov Evgeniy V Sharapova Tеtyana I popup.nrat_date 2022-03-09 Close
