摘要: AbstractThe action of sodium nitrite as a corrosion inhibitor for mild steel in neutral aqueous solution has been studied relation to the surface preparation steel, presence aggressive salts solution, and temperature.Surface little effect on minimum concentration required protection distilled water. In solutions containing anions linear exists between logarithm maximum anion that will permit inhibition. low order aggressiveness is sulphate > chloride nitrate; changes with increase concentration. Corrosion non-inhibiting nitrite/aggressive frequently severely localised form. A 5-fold requirement inhibition abraded water found 5° 70°, further large, ra...
