Электрохимическое поведение пластически деформированного титана в растворах серной кислоты

Electrochemical behavior of large-grained (average grain size is 15 µm) and submicrocrystalline titanium (average size of the elements of grain-subgrain structure is 0,15 and 0,46 µm) in 1...5 М H 2 SO 4 solutions has been studied. Significant differences in velocity ratio of anode and cathode processes as well as potential values of titanium transition into passive state depending on its structure and oxide layer composition were shown. The influence of Ti structure on its hydrogenation level and the type of sample corrosive attack in H 2 SO 4 was shown. The explanation of Ti behavior differences considering the increase of the content of oxygen dissolved in metal during severe plastic deformation while forming submicrocrystalline structure was proposed.
