Abstract The inhibition effect of Na₂MoO₄-organophosphorus A complex inhibitor on the corrosion of carbon steel in 55%LiBr+0.07 mol/L LiOH solution was studied by weight-loss tests, electrochemical measurements, AFM and EMPA. The results show that Na₂MoO₄-organophosphorus A complex inhibitor performed excellent inhibition in the solution. When its concentration reached 800 mg/L in 55%LiBr+0.07 mol/L LiOH solution at 240 ℃, the corrosion rate of carbon steel decreased to 43.2 μma^-¹, the anodic passivation region broadened and the passive current density of carbon steel decreased, the inhibition efficiency was 94.4%. At the same time, the charge transfer resistance increased. The compact compound film formed on the surface of carbon steel in 55% LiBr+0.07 mol/L LiOH solution containing the inhibitor. The film with island structure was mainly composed of iron oxide and molybdenum oxide.

Key words: carbon steel LiBr organophosphorus Na₂MoO₄
