Commercially available inhibitors were successfully investigated for their effectiveness in reducing the corrosion susceptibility of the turbo expander and steam/gas turbine industry alloys. However due to the fact that the power generating system is complex and consists of a multi-alloy system the investigation was expanded to study the corrosion behavior and stress corrosion susceptibility of other alloys such as copper brass (C36600 (38% Zn) Eco-brass (21% Zn) and red brass (8% Zn) nickel plated-copper and titanium alloys (grade 5 and grade 23) in the presence of these inhibitors. Electrochemical behavior (cyclic polarization and EIS) of these alloys in a 200 ppm Cl- solutions + different percentages of inhibitor showed significant improvement in passivity breakdown potentials and their critical pitting temperature. The data acquired from EIS tests showed that inhibitor adsorption to the alloy surfaces fits with the Langmuir adsorption isotherm; the enthalpy of adsorption is about -10 to -16 kJ/mol suggesting that this chemical compound provides physisorption to the surfaces of these alloys. No susceptibility to environmentally-assisted cracking using ASTM G44 and G38 standards was observed.
