摘要

研究了柠檬酸一水添加剂对铝在含有镓铟化合物添加剂的90%乙醇溶液中的阳极溶解和腐蚀速率的影响。结果表明，在溶液中加入一水柠檬酸可以在不降低铝的阳极溶解速率的情况下降低铝的腐蚀电流。当溶液中加入5 × 10-4 M的一水柠檬酸时，其缓阻率为58%。该电解质中的放电恒流曲线包含一个放电平台，电流密度高达16 mA/cm2。

Anodic Dissolution and Corrosion of Aluminum in KOH Solutions in 90% Ethanol Containing Additives of Gallium and Indium Compounds. Inhibitory Effect of Citric Acid

The effect of citric acid monohydrate additive on the anodic dissolution and corrosion rate of aluminum in the KOH solutions in 90% ethanol containing additives of gallium and indium compounds is considered. It is shown that an addition of citric acid monohydrate to the solution enables reducing the aluminum corrosion current without decreasing its anodic dissolution rate. When 5 × 10^–4 M citric acid monohydrate is introduced into the solution, its inhibition efficiency is 58%. The discharge galvanostatic curves in this electrolyte contain a discharge plateau up to a current density of 16 mA/cm².
