The electrochemical polarization method was used to study the inhibitive action of LiOH, Li2CrO4, and BTA, either individually or in different combinations. Afterwards, weight-loss tests planned by orthogonal arrays were carried out to find the optimum condition for the minimum corrosion rate for copper and mild steel in LiBr solution. The results from both polarization and weight-loss tests were consistent for each other in this study. The optimum condition predicted by the orthogonal-array experiments for the minimum corrosion rate is found out by adding 1.5 g/L LiOH, 4.5 g/L Li2CrO4, and 100 mg/L BTA, whose efficiency of inhibition is about 83% for copper and 99% for mild steel.
