Abstract The change of electrochemical noise(ECN)patterns wi th time of 16Mn steel in 0.1 mol/L Cl-+0.5 mol/L NaHCO3 solution was inv es tigated.The experimental result showed,during metastable pit initiation period,t he pitting initiation rate λ was less than 0.002 s-1,and the average life time of current transient coupled in ECN was about 3～5 s.However,the average li fetime of potential transient was 200 s.During the transition from metastable to stable pitting,λ increased rapidly,with an increase of the lifetime of current transient and a decrease of potential transient.Then,during the stable developm ent of pitting corrosion,the lifetime of current and potential transient become almost identical,and a large-scaled fluctuation in ECN as well as a decrease of λ was observed.In addition,during the transition from metastable to stable pitt ing,noise resistance Rn decreased fast,and Rn get stable once the st abilization of pitting corrosion.

Key words: 16Mn steel localized corrosion electrochemical noise i nitiation rate noise resistance
