Electrochemical tests were conducted to evaluate the inhibition effects of a commercial sodium nitrite (NaNO{sub 2})/sodium tolyltriazole (nitrite/TTA)-based corrosion inhibitor added to deionized water at 50 C. General and pitting corrosion of materials commonly used in closed cooling water systems were examined. Tests also were performed in deionized water to which Cl{sup {minus}} had been added. At the tested concentrations, nitrite/TTA was found to be an effective corrosion inhibitor for all of the materials tested in plain deionized water and Cl{sup {minus}}-containing water.
