... candidates, both organic and inorganic in nature. Recently, a nitrate-based compound has been proposed as a corrosion inhibitor, as nitrates are still used in concrete as set accelerators. Nitrates inhibiting mechanism is similar to nitrites, the latter being the most efficient compound nowadays available...

... of nitrates and nitrites on rebar corrosion. FIGURE 2. Calculated concentration of completely dissociated nitrate ions in a mixture of calcium nitrite and nitrate at a pH of about 12. (OLI Studio ^† 10.0.1.24 ⁽²⁾ ). Five factors, i.e., OH⁻, Cl...

... while nitrite, hydroxide, and carbonate are inhibitive species. The role of nitrate and nitrite in localized corrosion and cracking appear to be related to their effects on active dissolution and passivity, rather than on corrosion potential. The long-term corrosion potential is influenced mostly...

... water and of an oil production formation water. The results demonstrate the effectiveness of this technique and show that nitrite, as an example of a cooling water inhibitor, can be effective in retarding the rate of propagation with the appropriate dosage. Tests in simulated oil production formation...

...J. Leifer; P.E. Zapp; J.I. Mickalonis Statistical models were developed to predict the occurrence of pitting corrosion in carbon steel (CS) waste storage tanks exposed to radioactive nuclear waste. Levels of nitrite ( NO 2 − ) concentrations necessary to inhibit pitting...

...T.D. Burleigh; A. Paris; K.H. Chan; M. Okuma; H. Katayama Photoelectrochemistry was used to study the inhibited films that formed on mild steel in aerated municipal water. Tests included three types of inorganic inhibitors that contained as active ingredients either molybdate, nitrite, or zinc salt...

...C. M. Mustafa; S. M. Shahinoor Islam Dulal The use of molybdate (MoO₄²⁻) and nitrite (NO₂⁻) as corrosion inhibitors for mild steel galvanically coupled to copper was investigated. In simulated cooling water (SCW), galvanic contact of copper is harmful...

...D.B. Alexander; A.A. Moccari Electrochemical techniques were used to study the inhibition effects of molybdate (MoO₄^2–), MoO₄^2–+ nitrite (NO₂^–), MoO₄^2– + tolyltriazole (TTA...
