Abstract
1. In the cathodic polarization of a titanium electrode in acid and alkaline solutions, the hydrogen evolved interacts with the metal of the cathode. The composition and structure of the compounds of titanium with hydrogen formed, depend upon the electrode potential, the nature of the electrolyte, the current density, and the time of treatment. 2. Under certain conditions of cathodic polarization, simultaneously with the formation of titanium hydrides, a breakdown of them is observed. The ratio of the rates of formation and decomposition of the hydrides depends upon the electrode potential and the nature of the electrolyte. 3. The evolution of cathodic hydrogen on the surface of titanium, freed of oxides, occurs at high negative potentials. With increasing saturation of the surface of the titanium electrode with hydrogen, its potential is shifted in the direction of electropositive values.
