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.

羟乙基纤维素在琥珀酸二辛酯磺基钠盐存在下对Al 6060在4m NaOH中的缓蚀作用增强

研究了羟乙基纤维素（HEC）作为铝6060合金缓蚀剂在4 M NaOH电解液中对铝空气电池的腐蚀性能。通过失重、析氢、动电位极化（PDP）、线性极化电阻（LPR）和表面评估来测试HEC的功效。在碱性溶液中，HEC表现为混合型缓蚀剂。其效力随剂量的增加而增加。二辛基磺基琥珀酸钠盐（DOS）的协同作用提高了性能。SEM/EDAX、FTIR和光学轮廓仪显示，HEC单独和与DOS联合使用通过吸附在金属表面来减少强碱性介质中铝合金的腐蚀。HEC + DOS可以作为一种潜在的铝空气电池电解质添加剂。
