Effect of heat treatment on the corrosion behaviour of Ti–5Ta–1.8Nb alloy in boiling concentrated nitric acid

Microstructure and Electrochemical Behavior of in Vitro Ti-26Nb, Ti-26Zr and Ti-26Ta Alloys Processed by Levitation Melting Technique

“…The polarization curves confirm the formation of a passivation film for all the studied alloys, the same behavior which was observed in the study of open circuit potential. Formation of the passivation film for Ti alloys is also reported by other authors [22][23][24][25]. It can also be verified from the study that alloy Ti-26Ta showed corrosion resistance similar to that obtained for the alloy Ti-26Zr.…”

Structure and corrosion resistance of Ti-Nb layers obtained by non-vacuum electron-beam cladding on CP titanium substrates

“…However, using titanium and its alloys under extreme conditions, such as boiling solutions of nitric acid, is restricted due to their low corrosion resistance [4]. Alloying titanium with refractory elements, such as niobium and tantalum, leads to increasing corrosion resistance [5][6][7]. At the same time, alloying with niobium is more preferable, since this element is similar to tantalum in corrosion characteristics in oxidizing acid solutions, but it is considerably lighter and cheaper.…”

Influence of rolling and heat treatment on the structure and properties of the coatings fabricated on the titanium substrates by electron beam cladding

“…В этом случае высоколегированные сплавы на основе железа могут быть заменены на титановые сплавы [4]. В работах [5][6][7][8] было показано, что особенно эффективным является использование сплавов системы «титан-тантал». Так, например, уровень коррозионной стойкости титанового сплава, содержащего 40 % тантала, сопоставим с уровнем коррозионной стойкости технически чистого тантала [2,5].…”
