Abstract The characteristics of current fluctuations on carb on steel in phosphate+borate buffer solutions containing chloride were studied u sing electrochemical methods.Current fluctuations were recorded at pitting poten tial Eb or above Eb during both potentiostatic and potentiodynamic polarization. Although the background current did not show continuous increase,pits were obser ved after the test,which may be the result of repeated metastable dissolution ar ound the active sites on the surface.At constant potential,the fluctuation frequ ency decreased with time,and the peak currents follow normal distribution.Increa sed potential led to higher peak currents,but exerted no influence on the fluctu ation frequency.All the current peaks have the type of quick increase and slow decay in exponential forms.The mechanism of pitting of mild steel in the system was discussed.

Key words: mild steel pitting current fluctuation
