Abstrakt: In this study corrosion resistance of the coatings obtained on VТ14 (4% Al, 3% Mo, Ti - the rest) titanium alloy substrates using focused electron beam with an energy of 1.4 MeV injected into the atmosphere was discussed. The two-layered material fabricated on the titanium substrate can be applied for corrosive-resistant reactors used in chemical industry. These reactors are exposed by nitric acid heated to approximately boiling temperatures. It was shown that in spite of penetration of alloying elements (Al and Mo) from the substrate to the coating, high anticorrosive properties of the coatings can be achieved. For this purpose, high alloying degree of the coatings with such corrosive resistant elements as Ta, Nb and Zr should be provided. [ABSTRACT FROM AUTHOR]
