The influence of different aggressive anions on the electrochemical behaviour of aluminium in sodium nitrate aqueous solutions (original) (raw)
2000, Materials and Corrosion
AI-generated Abstract
The research investigates the electrochemical behavior of aluminum in sodium nitrate solutions, focusing on the impact of aggressive anions such as chloride, thiocyanide, hydroxyl, sulfide, formate, and acetate. Various experimental techniques were employed to assess the critical pitting and protection potentials, revealing that these anions can cause extensive localized corrosion by affecting the surface oxide film. The findings suggest mechanisms involving the complexation of aluminum ions and highlight the potential of adsorptive inhibitors to mitigate localized corrosion.
