Abstract The effect of piperidine (PD) on inhibition from the damage of passive film of Cr25 stainless steel in NaCl solutions of various concentrations was investigated by potentiodynamic anodic polarization, P-G transient response measurements and electrochemical impedance spectroscopy (EIS). The results showed that the stability of passive film on Cr25 steel was remarkably improved by PD. In NaCl solution, the "Critical Ratio" of PD concentration to Cl- concentration was determined: PD: Cl- = l:100-170 (mol.). When the ratio of PD to Cl- concentration was greater than the "Critical Ratio", film breakdown potential was almost not influenced by PD and Cl- concentrations. On the contrary, when the ratio was less than the criterion, the notable dependence of film breakdown potential on PD and Cl- concentration was observed. The inhibition mechanism of PD was discussed in terms of the competitive adsorption theory. The similarities and dissimilarities between Cr 25 and 304 stainless steels in inhibition of PD were compared. In addition, a physical model was suggested fof the explanation of the above-mentioned results on the basis of photo-electrochemistry and Mott-Schottky plots measurements.
