“…The inhibitive effect may be affected by the size and the bond strength of the adsorbed molecule and in dislodging chloride from the sites through which it preferentially penetrates the passive oxide layer (Bellanger, 2006;Ilevbare & Burstein, 2003;Ilevbare et al, 2005). An inhibitor may penetrate or be pulled through the oxide fi lm under the infl uence of the electric fi eld provided that it is not much larger than Cl -.…”

The application of stainless steels and chromium containing nickel-based alloys is limited by their susceptibility to localized corrosion in the forms of pitting and crevice corrosion or environmentally assisted cracking. Inhibitors may be normally found in service environments or added on purpose to mitigate or avoid the effects of aggressive agents such as chloride ions. The present study critically reviews the present knowledge on inhibition of chloride-induced pitting and crevice corrosion. Pioneering studies and recent fi ndings are analyzed in light of the present theories for describing the localized corrosion processes. This review particularly focuses on the inhibition of crevice corrosion of alloy 22, which has been thoroughly studied in the past decade.

“…10 and Table 3). These oscillations are due to the nucleation of unstable species in active and prepassive regions and repair process associated with the propagating stress [28,34] and changes in the composition of the oxide surface. Stress of the oxide layer is caused by non stable Ti II and Ti III presence in oxide [10], whereas stable oxide layer is caused by total Ti IV formation.…”
