Static and dynamic corrosion of galvanized steel in 4.6 M lithium bromide (LiBr) solution at 20 C and at 70 C was studied using a new polarographic method for the determination of zinc (Zn) in LiBr solution. Static and dynamic corrosion of galvanize steel at 20 C and 70 C followed a linear tendency with exposure time. However, a change in the slope of dynamic corrosion was observed at 20 C. The corrosion product was studied using energy dispersive x-ray analysis (EDXA) and x-ray diffractometry and was considered to be a mixture of zinc hydroxide Zn(OH)[sub 2] and oxides. The corrosion product morphology was amorphous and gelatinous at 20 C and crystalline at 70 C.
