On the importance of irreversibility of corrosion inhibitors for active coating protection of AA2024-T3
چکیده انگلیسی
Inhibitor leaching, fast, effective and irreversible passivation are essential for active protective coatings to protect aluminium alloys. This study presents the comparison of the active protective properties of lithium carbonate and two organic corrosion inhibitors, benzotriazole and 2-mercaptobenzothiazole, on aluminium alloy 2024-T3 with a special focus on the irreversibility of the inhibition. A combined approach of electrochemical measurements, optical observations, surface roughness and weight-loss measurements revealed the reversible inhibition behaviour of benzotriazole and 2-mercaptobenzothiazole on AA2024-T3. On the contrary, lithium carbonate demonstrated fast, effective and irreversible corrosion inhibition, providing the essential characteristics needed for effective active corrosion protection from coatings.
