The composition and structural features of deposited coatings, mechanical and corrosion properties are optimized. The influence of the composition and structural state of the developed coatings on their physical and mechanical properties (microhardness, resistance to corrosion and cavitation and abrasive wear) has been studied. It is shown that the optimal combination of mechanical properties and high resistance to oxidation from a series of studied coatings FeCr, FeCrAl and CrAl have coatings FeCrAl system with a concentration of Cr ~ 22 at.% and Al ~ 14.3 at.%. It was found that protective coatings of FeCrAl type FeCrAl and CrAl with a thickness of ~ 12 μm significantly increase oxidation resistance and prevent the destruction of fuel rods under oxidation conditions in air at a temperature of 1150 ° C for 1 hour.  Product Description popup.authors Belous Vitaly A Kuprin Olexander S Tikhonovsky Mykhailo A popup.nrat_date 2020-12-23 Close
