摘要	An investigation was carried out on the features of potential fluctuations of AISI type 321 stainless steel under various constant loads in acidic sodium sulphate solutions with or without the addition of chloride ions. The probability of occurrence of potential noise was found to be affected by the stress level, the concentration of Cl- and the acidity of the solution. It increased with increasing stress and concentration of Cl-. However, increasing acidity led to a decrease in the potential noise level. The probability of potential noise fluctuations decayed gradually with increasing time after loading. Based on a mechanism of the breakdown and repassivation, a statistical analysis has been undertaken of the potential fluctuations recorded in the present study.
