Abstract
Hydroxyethyl cellulose (HEC) was tested as an Al 6060 alloy corrosion inhibitor in 4 M NaOH electrolyte used in Al-air batteries. HEC’s efficacy was tested using weight loss, hydrogen evolution, potentiodynamic polarization (PDP), linear polarization resistance (LPR), and surface assessments. In alkaline solution, HEC behaves as mixed-type corrosion inhibitor. Its effectiveness increased with increase in dosage. Synergy from dioctyl sulfosuccinate sodium salt (DOS) improved performance. HEC alone and in combination with DOS reduced Al alloy corrosion in the strong alkaline medium by adsorbing on the metal surface, as demonstrated by SEM/EDAX, FTIR, and optical profilometer. HEC + DOS could serve as a potential electrolyte additive for Al-air batteries.
