Abstract

Structural defects have an impact on the process of reversible hydrogen sorption in metals. They alter the kinetics of absorption and the hydrogen content in unit volume. A comparative analysis of the kinetics of formation of hydrogen segregations for an edge dislocation, the top of the microcracks and wedge disclinations. As an illustrative example we consider the electrochemical system "nickel-boron-hydrogen bond." The kinetics of the process for the wedge disclination obeys a linear law. Hydrogen segregation to the top of microcracks and edge dislocation occurs more slowly. Hydrogen is considered the capacity mentioned structural defects. It has been shown that they do not significantly increase the amount of hydrogen per unit volume. The results of the theoretical analysis are attracted to justify limiting possibilities metals reversible hydrogen sorption.
