Inhibition of the corrosion of carbon steels by lithium molybdate in bellow 21.4mol/kg-H20 alkaline lithium bromide aqueous solution was investigated in glass sealed tube at various temperatures.Lithium molybdate gives an excellent corrosion inhibition for carbon steel even at a concentration as low as 0.003mol/kg-H20 in the presence of 0.36mol/kg-H20 lithium hydroxide.In addition, this inhibitor is effective in the temperature range from 373 to 473K. It is concluded that the corrosion inhibition action by lithium molybdate results from the passivation of carbon steel by the compact film composed of molybdenum oxide such as MoO2 and Fe3O4 formed on the surface of carbon steel, which inhibits anodic reaction.
