Аннотация

Electrochemical and corrosion behavior of coarse-grained (average grain size of 15 μm) and submicrocrystalline titanium (two types with the average grain-subgrain structure size of 0.15 and 0.46 μm) is studied in 1-5 M H 2SO4 solutions. A significant difference is shown in the ratios of anodic and cathodic process rates and also potentials of transition of titanium into a passive state as a function of its structure and the oxide layer composition. The effect of the Ti structure on its degree of hydrogenation and type of corrosion damage of samples in H2SO4 is shown. The difference in the behavior of Ti in solutions is explained on the basis of increased content of oxygen in the metal owing to an increase in diffusion permeability of plastically deformed titanium.
