Corrosion monitoring techniques were performed on X70 steel in saline solution sat- urated with CO_2 with and without thiourea additives within the concentration range 5-25 mg/L.It was found that when the concentration of the inhibitors were increased, the inhibitor efficiencies(IE)of thiourea varied with solution temperature and immer- sion time.The results indicated that thiourea had the highest inhibition efficiency. The potentiondynamic polarization studies revealed that thiourea are mixed-type in- hibitor that mainly restrains the anodic process.
