Défauts des matériaux. Protection des matériaux Résumé : The corrosion inhibition of a 70 wt% Cu–30Ni alloy in a 55 wt% lithium bromide (LiBr) + ethylene glycol + H2O by inorganic inhibitors has been evaluated at different temperatures by using electrochemical techniques. Inhibitors used included lithium chromate (Li2CrO4), lithium molybdate (LiMoO4), and lithium nitrate (LiNO3), in a concentration of 5 ppm at 25, 50, and 80 °C. Employed techniques included potenthiodynamic polarization curves, linear polarization resistance, and potentiostatic measurements. Results have shown that the alloy had an active–passive behavior at 25 and 50 °C, and the passive film properties were improved with the addition of inhibitors, whereas at 80 °C the inhibitors did not have any effect. Similarly, in general terms, the best corrosion performance at 25, 50, and 80 °C was obtained by adding Li2CrO4, LiNO3, and LiMoO4, respectively. However, the alloy was not susceptible to pitting corrosion in presence of inhibitors but it was highly susceptible towards pitting type of corrosion in absence of inhibitors.
