Abstract Electrochemical methods were employed to investigate galvanic corrosion behaviors of super 13Cr and P110 couples in NaCl solution. Corrosion morphology and products of the couples were characterized by SEM, EDS and XRD. The results showed that there were obvious potential difference between super 13Cr and P110 steel in NaCl solution. When they were contacted, the super 13Cr-P110 steel couples of electric current density would form the serious galvanic corrosion, P110 was accelerated to corrode as anode and super 13Cr was protected as cathode in the coupling. With the increase of S_c/S_a, the galvanic current increased obviously and anode corrosion was aggravated, the corrosion products was FeO. The form of corrosion damaged was change from loose corrosion products to corrosion film cracking layer falling off.
