Аннотация

How tensile stresses and pH value influence the passivation, corrosion, and structure of a protective film of two-phase titanium alloy VT22 in 3% solution of NaCl is investigated with the help of potentiometry, potential and dynamical analysis, and electrical and chemical impedance spectroscopy. We simulate the process of electrical transfer through the protective film and we reveal that its structure is two-layered. The film consists of a layer based on titanium hydroxide under which there is a titanium oxide layer adjacent to the alloy and primarily it protects the alloy against corrosion. How tensile stresses and pH value influence the hydrogen saturation process and delayed fracture of titanium in an aqueous NaCl solution is investigated.
