Interaction of the Linear-Connected Pittings
Abstract: In this work, the mechanism of interaction of pittings, occurring on the heterogeneous surface of the passivated metal at presence in an aqueous electrolyte solution the activating (halide) anions is developed. A mathematical scheme describing this mechanism is presented. The equations for the currents density of the anodic dissolution of pitting as a function of concentration of activating anions and free water are obtained. The closed system of the equations representing a basis theory of an interaction of pittings is obtained.
