Abstract

Electrochemical methods were employed to investigate galvanic corrosion behaviors of super13Cr and P110 couples in NaCl solution at different temperature. Corrosion morphologies and products of the couples were analyzed by SEM, EDS and XRD. The results showed that there were potential difference distinctly between super 13Cr and P110 steel in NaCl solution at different temperature, when its contacted, galvanic corrosion of super 13Cr-P110 steel couples will occurred. P110 was accelerated to corrode as anode and super 13Cr was protected as cathode in the coupling. Super 13Cr-P110 steel couples could not be used as P110 without any protection in NaCl solution at 20˚C to 80˚C. Corrosion current density and galvanic corrosion of super13Cr-P110 steel couples increased with increasing temperature in NaCl solution, of which corrosion products are Fe3O4.
