摘要：
Relaxation kinetics of the metal dissolution current after pulsed anodic activation are analyzed using a model of spatial separation of the dissolution and passivation of hydrophilic metals. The current rise is contributed to mainly by the formation of new step sources resulting from the desorption of blocking oxygen atoms from vertexes of trihedral pyramids that are formed in excess quantities during the activation pulse.
