Preferred Label : activation;
Detailed label : activation in electrochemical corrosion;
IUPAC definition : The process of transition from the passive to the active state by removal of the passivating
film. A necessary condition for activation is an electrode potential negative to the
equilibrium potential of formation of the passivating film. Activation is achieved
by cathodic currents, by a reduced substance in the adjacent solution, or by contact
with an electronic conductor having a suitably negative corrosion potential.;
