Sensitivity of Corrosion Behavior for Fe-Based Amorphous Coating to Temperature and Chloride Concentration

چکیده
The effects of solution concentration and temperature on the electrochemical behavior Fe-based amorphous (AMCs) coatings in NaCl were studied by using conventional measurement XPS analysis. Results indicated that as increased, current density for AMCs increased pitting potential decreased. This reduced corrosion resistance was derived from decreased passivation index polarization resistance, which contributed to decrease induction time (tm) initiation pit. passive films formed exhibit two types’ semiconductors higher lower flat band potential. protectiveness film mainly correlated with reduction Cr2O3 content, increase carrier work function (WF).
