Abstract The influence of Cl-,SO42-,PO43- and Cro42- anions on the nucleation,growth and repassivation rates of metastable pitting of an amorphous alloy was studied using potentiostatic polarization method.During the repassivation period of metastable pits,the relation between current and time followed Imax I=R(t-tmax),with the repassivation rate parameter R following a lognormal distribution.Increased Cl- concentration resulted in faster nucleation and growth rates for metastable pits.The presence of SO42-,PO43- and CrO42- anions decreased both the nucleation rate and the growth rate of metastable pits.The inhibitive effects of these three anions on nucleation and growth of metastable pits decrease in the order:CrO42->PO43->SO42-.The anions affected the R values only in a very small extent.

Key words: metastable pitting anions growth rate
