PREPARATION OF LITHIUM MOLYBDATE AND ITS CORROSION INHIBITION TO CARBON STEEL IN LITHIUM BROMIDE SOLUTION
钼酸锂的制备及其对碳钢在溴化锂溶液中的缓蚀作用

Lithium molybdate was prepered by neutialization of lithium bydroxide by molybdic acid,and its corrosion inhibition to carbon steel in lithium bromide solution was studied by way of weigh loss and polarization measurements.The film formed on carbon steel is observed by SEM and characterized by X-ray diffraction.It reveals that lithium molybdate induces inhibition effect to carbon steel in lithium bromide,it decreases effectively the corrosion of carbon steel in lithium bromide by adding 0.20 mol/L lithium hydroxide and 0.02 mol/L lithium molybdate.It assumed that the complex film of ferric oxide,lithium molybdate and molybdenum oxide formed on carbon steel decrease the corrosion of carbon steel through inhibition of anodic reaction.
