Corrosion of Spray Formed Hypereutectic Al-Si-X Alloys in Alcoholic Fuel

In this study the corrosion behavior of two high silicon aluminum alloys produced by spray forming and a cast iron has been evaluated in alcoholic medium. The comparative results obtained by visual observation and electrochemical impedance spectroscopy are discussed. All tested materials showed extremely low corrosion rates in a commercial alcoholic fuel used as the corrosion test medium.
