Abstract
This article discusses the results of corrosion tests and microstructural studies of forgings from various titanium alloys modified with ruthenium, of systems Ti–Al–Zr + 0.15% Ru, Ti–Al–V–Mo + 0.15% Ru, Ti–Al–V–Cr–Fe–Mo + 0.15% Ru and similar systems of basic compositions. On the basis of the performed complex of studies, the influence of the amount of the β-phase on the local content of ruthenium and, as a consequence, on the effect of cathodic protection in general was analyzed.
Supporting agencies: Experimental studies were performed on the equipment of the Center for Collective Use “Composition, Structure and Properties of Structural and Functional Materials” of the NRC “Kurchatov Institute” – CRISM “Prometey”.
