摘要

This study presents work on corrosion of aluminum, Al-.5% Cu, and Al-2% Cu. Electrochemical tests were performed in dilute HF solutions both with and without CO(sub 2) sparging. It is suggested that CO(sub 2) or its reaction products interact with the passive film so that exposure of Cu in the oxide-solution interface is minimized. CO(sub 2) is investigated as a corrosion inhibitor. 4 refs. (JDL)
