ELECTROCHEMICAL AND AES INVESTIGATIONS OF SOME METALLIC GLASSES IN SULPHURIC ACID SOLUTION.
(1987) I.B. Singh; R.D.K. Misra; T.K.G. Namboodhiri; R.S. Chaudhary
No passivation is observed for 0040 alloy whereas all the other alloys passivated in sulphuric acid solutions. Initial dissolution of the alloy in the active region is essential for passivation in molybdenum containing alloys and the concentration of Mo in the passive film is less than that of in the bulk of the alloys. Better passivation is observed in 2826 alloy when the dissolution rate is high in the active region. Prepassive film on 2826MB and 2826 alloys is nickel rich which changes to iron rich passive film at higher anodic potentials. In 2826A alloy, chromium and phosphorous concentrations are higher in the passive film.
