Short-circuited galvanic cells which can emerge in corrosion-mechanical cracks

We consider the distinct features of the functioning of galvanic cells which cause the evolution of corrosion cracks under stress. We determine the electrochemical characteristics of a cell formed due to differential hydrogenation and their dependence on the ratio of areas of the anode and cathode f...

Description
Summary:We consider the distinct features of the functioning of galvanic cells which cause the evolution of corrosion cracks under stress. We determine the electrochemical characteristics of a cell formed due to differential hydrogenation and their dependence on the ratio of areas of the anode and cathode for a number of structural materials. On the basis of the data obtained, we propose an interpretation of the mechanism of evolution of corrosion and mechanical cracks.
