In works [1,2] it has been established, that interaction of hydrogen with metal at its electrochemical restoration is carried out on defects of structure (intergrading borders, exit places on a disposition surface, interphone borders) Generally with metal it is possible to present process of electrochemical interaction of hydrogen in the form of elementary reactions:formulawhere Meo Δ defect of structure of metal. It is possible with sufficient degree of reliability to assume, that the stage of formation of hydride of metal (5) precedes stage molizatsii hydrogen from free atoms (4). As defects of metal structures considerably differ on the potentials energy of formation of hydrides will differ also, and according to it will be various and temperatures экстракции hydrogen from these connections. According to the aforesaid there are all bases to believe, that the semi width of peak of an internal friction on curve dependence Q-1 = f (T) also will be various. In work [1] dependence of peaks of an internal friction for galvanic coverings on the basis of d-elements from which follows is received, that inclinations of ascending and falling sites of a curve are various on a steepness. It testifies to distinction in speeds диффузионных processes at temperature change. Quantitative definition of hydrogen by a method of an internal friction has shown, that the height of peak of an internal friction changes according to quantity of hydrogen which is absorbed at secondary hydrogenation the sample. Analytically this dependence to define with high degree of accuracy it is inconvenient, owing to impossibility of identification of defects of structure on values of potentials and their volume density in unit of volume of the examinee of the sample. On the other hand, in electrolytic metals probably presence of close pores where molecular hydrogen is localized. Definition, which probably method of an internal friction only in a working interval helium temperatures ~ 4,2 To. In work [3] the comparative analysis of hydrogen capacity of various structural defects in electrochemical systems on the basis of nickel is carried out. Generally, the number of defects can be defined expression: nd ≡ k · ik · Cboron · f (pH), where nd − number of defects; k − the proportionality factor depends by nature electrolytes’; Cboron − concentration boron a component in electrolyte; ik − cathodes density of a current; f (pH) − functional dependence from pH.
