Effects Of Anodic Protection On SCC Behavior Of X80 Pipeline Steel In High-pH Carbonate-Bicarbonate Solution

Abstract: The potentiodynamic polarization test and slow strain rate tensile tests of X80 pipeline steel were performed in 0.5M Na 2 CO 3 -1M NaHCO 3 solution to study the electrochemical and stress corrosion cracking properties. The results of potentiodynamic polarization test show that there is an obvious stable passive region, about from 0v to 0.8V (SCE), indicating that anodic protection is feasible. The results of slow strain rate tensile tests show that the stress corrosion cracking sensibility is high and cathodi… Show more

“…The stable passive region provides the possibility of anodic protection as the potential increases to about 0 v vs. SCe. in a stable passivity region, Fe can be oxidized to Fe 3 o 4 directly, which can be further oxidized to Fe 2 o 3 , as follows [44]:…”
