The aim of the work is to create scientific bases and methodology of electrochemical synthesis of the latest composite coatings based on alloys of iron family with refractory metals, which, thanks to a range of unique properties, provide effective and reliable protection against destruction and wear of metal parts of civil and military purposes. materials in power generating devices, magnetic characteristics and microhardness for information storage devices, sensitivity of sensor elements. Research methods - linear and cyclic voltammetry, chronopotentiometry, X-ray diffraction microanalysis and X-ray fluorescence analysis, scanning electron microscopy, scanning probe atomic force microscopy using fractal analysis, impedance microbiotrium, spectrometry, magnetometry spectroscopy. The relationship between the composition and morphology of cobalt-based coatings and their physico-mechanical and physico-chemical properties has been experimentally established. The increase of microhardness of coatings relative to alloys-forming components is proved. A variable technological scheme of electrodeposition of alloys and composites based on cobalt and iron with refractory metals has been developed, which allows to obtain both thin-film materials of special purpose a Product Description popup.authors Ermolenko Iryna Yu Korohodska Alla M popup.nrat_date 2022-03-09 Close
