- Аннотация: The first results of manufacturing and investigations of a new type of nanocomposite protective coatings are presented. They were manufactured using a combination of two technologies: plasma-detonation coating deposition with the help of plasma jets and thin coating vaccum-arc deposition. We investigated morphology, physical and mechanical properties of the coatings of 80-90 mu m thickness, as well structure, as defined the hardness, elastic Young modulus and their corrosion resistance in different media. Grain dimensions of the nanocomposite coatings on Ti-N-Cr base varied from 2.8 to 4 nm. The following phases and compounds formed as a result of plasma interaction with the thick coating surface were found in the coatings: Ti-N-Cr (200), (220), gamma-Ni(3)-Fe, a hexagonal Cr(2)-Ti, Fe(3)-Ni, (Fe, Ni)N and the following Ti-Ni compounds: Ti(2)Ni, Ni(3)Ti, Ni(4)Ti, etc. We also found that the nanocomposite coating microhardness increased to H = 31.6 +/- 1.1 GPa. The Young elastic modulus was determined to be E = 319 +/- 27 GPa - it was derived from the loading-unloading curves. The protective coating demonstrated the increased corrosion resistance in acidic and alkaline media in comparison with that of the stainless steel substrate. (c) 2009 Published by Elsevier Ltd.
