摘要：

We propose a model of absorption of hydrogen by titanium alloys in the process of chemical etching. We obtained a solution that describes the amount of absorbed hydrogen and its distribution in the metal as a function of the rate and time of etching. On the basis of the equations obtained, we developed a method for determination of the diffusion coefficient of hydrogen in a metal. The essence of the method is a sequential etching of a specimen in hydrogenated and nonhydrogenated solutions and determination of the amount of hydrogen which remains in the metal. The effective diffusion coefficients of hydrogen in titanium alloys with various structures are found.
