Abstract :
to minimize the metal corrosion, a new glass system (100-x) NaPO3-xTiO2 (x=0 and x=3% mol) have been synthesized the electrochemical and theoretical investigations were used to study their anticorrosive performance for the mild steel (MS) in 3% NaCl medium. NaPO3 and 97 NaPO3-3TiO2 act as great inhibitor for mild steel in 3% NaCl. In the other hand, the surface of the mild steel has been analyzed by the scanning electron microscopy SEM. In addition the inhibition efficiency was found to increase with the increase of the inhibitors concentration and immersion time due to the formation of protective the film on the substrate surface
