Organic inhibitor benzotriazole (BTA) are effective in reducing the copper corrosion due to the formation of an insoluble and complex film, whereas its reliability is decreased with the increasing temperature of LiBr aqueous. The corrosion behaviors of high-chromium, high-molybdenum and high-nickel alloys in LiBr solution have been studied through an electrochemical method.[17-23] Though these alloys have strong corrosion resistance to general corrosion of carbon steel, the pitting corrosion still occurs in concentrated LiBr solutions at high temperature.[24-26] Moreover, the corrosion rate of Cu-Ni alloys in 65 wt. % LiBr aqueous solution at 173 oC still reaches 130.00 μm/y.[27]
