Abstract  A Strict thermodynamic definition of the critical pitting potential (φcb)has been proposed. A model of pitting initiation was developed and the equation of φcb=α-blnα_(X~-)was derived from the definiton and the model, α_(X~-) being the activity of the active anion. It is shown that φcb, α_(X~-),c and T_c (critical temperature) are correspondent to one another, Furthermore, the kinetics equation of pitting initiation was established and the equationof φb=φcb+H was obtained. The functional relations between induction time τ and α_(X~-) under various stationary applied potentials have been determined. The theory developed in the paper can explain many authors' experimental results, It is poossible for one to determine φcb practically.
