摘要

A study of the corrosion inhibition of 316L type stainless steel in LiBr (614 g/l) + ethylene-glycol+H2O by using inorganic inhibitors has been carried out by using potentiodynamic polarizationcurves, free corrosion measurements and linear polarization resistance measurements. Inhibitors0 include LiNO3, Li2MoO4 and Li2CrO4 at concentrations of 5, 20 and 50 ppm and at 25, 50 and 80 C.Polarization curves showed that the addition of 5 ppm of either inhibitor did not affect the corrosionbehavior of 316L SS. However, with the addition of higher inhibitor concentrations, both the corrosionand passivation current density values increased, reaching the highest values with the addition of 20ppm, but the passive region was widened and the pitting potential value was increased. At 25 and0 0 50 C the passive behavior of the steel was kept but it did not exist at 80 C. For long time testing, linearpolarization resistance measurements showed that the corrosion rate was not increased with theaddition of either 5 or 20 ppm but it decreased with the addition of 50 ppm of inhibitor. The corrosionresistance decreased with increasing the temperature but the inhibitor efficiency increased. Nitrateshad a slightly better performance than nitrates and molybdates.
