Abstract
The corrosion characteristics of the aluminum alloys were investigated in the bio-ethanol gasoline blended fuel at 100°C. The corrosion property of aluminum alloys was evaluated by an in-situ 2-electrode electrochemical impedance spectroscopy (EIS), weight loss test and time-pressure measurement. Surface analysis was carried out after immersion test. The impedance was increased at initial immersion time due to the formation of boehemite film (?- AlOOH); after that, it was decreased due to the initiation of aluminum alkoxide reaction. The pressure of autoclave was increased because of the hydrogen gas from the aluminum-ethanol alkoxide reaction. It was verified that a 2-electrode EIS and time-pressure measurements were able to evaluate the corrosion resistance of aluminum alloys in the bio-ethanol gasoline blended solution.
