Установка для измерения коэффициентов диффузии водорода методом вихревых токов в металлах при их наводороживании

Abstract

A method is proposed for measuring the diffusion coefficient of hydrogen in a membrane made of a titanium alloy VT1-0 based on the use of eddy currents and an installation for its implementation is described. An eddy current sensor is located on the membrane, which is the wall of the electrolytic cell. The diffusion process is measured under the conditions of formation of titanium hydrides. The formation of titanium hydrides during hydrogenation is monitored over time by measuring the diffraction spectra. The results of the measurement of the diffusion coefficient of hydrogen by the proposed method are given in the conditions of formation of titanium hydrides in the membrane. The results can be used to determine the diffusion coefficients of hydrogen in various structural materials, in space technology, nuclear power engineering, in products subjected to hydrogenation during operation.
