i and its alloys have been widely used in aerospace, and biomedicine, petrochemical industries because of their excellent
passivity. In this paper, the passivation and transpassivation behavior of pure Ti in artificial seawater was investigated by
means of volta potential, cyclic voltammetry, spectroscopic ellipsometery, Mott-Schottky analyses, SEM and XPS. The results
indicated that the passive Ti surface can transform to a relatively active state around at roughly 1.4 V
SCE
and then became passive
again at more positive potentials up to 3.2 V
SCE
. Based on these experimental results, a model was proposed to interpret the
transpassivaton behavior around that potential.
