  A multi-species reactive transport model based on the sequential
non-iterative approach is employed to investigate two major stages involved in
artificial pit experiments of stainless steel: I. Stable pitting under a salt
film and II. Film-free dissolution that transitions to repassivation. Data of
current density and electrical potential obtained from rapid polarization scans
of pits with different depths are utilized to calibrate the elapsed time and
the electrode kinetics of each stage. The local chemistry near the base of pits
at different temperature and bulk concentrations is simulated to determine
several critical electrochemical factors at saturation and repassivation.
