Choice of design parameters of base details at the design stage P.N. Komarov, A.A. Ruktuev In this paper we study structure and properties of cp-Ti surfaced alloyed with Ta and Nb. The surface alloying was done by non-vacuum electron beam cladding. The thickness of the high quality defect-free cladded layer reached 2 mm. The coatings had dendritic morphology with fine lamellar structure inside dendrites. The rate of corrosion of the best coatings in boiling 68 % nitric acid was 96 times less in comparison with pure Ti. Key words: surface alloying; electron-beam cladding; corrosion resistance; titanium alloys; metal powders
