چکیده:

Zirconium-based conversion coating was proposed as one of the most prospective alternatives to toxic chromate conversion coating on several metals and alloys. In this research, zirconium conversion coating has been applied on St-37 and CRS substrates. The electrochemical impedance spectroscopy (EIS) and DC polarization measurements were carried out to evaluate the coating corrosion performance. The results showed that the corrosion resistance of both substrates experienced a significant increment (
