Corrosion Aggressiveness of Ethanol-Gasoline and Butanol-Gasoline Blends on Steel: Application of Electrochemical Impedance Spectroscopy

Original language description

Nowadays, bioalcohols are promising renewable alternative fuels to gasoline in road transport. One of the most crucial issues of many alcohol fuels is limited information about their compatibility with fuel line materials such as steel. This study aims to evaluate the corrosion aggressiveness of alcohol-gasoline blends to mild and stainless steel. Two alcohol-gasoline blend types were tested: ethanol- and butanol-gasoline blends. These fuels were tested in a pure (noncontaminated) and contaminated form. The corrosion studies were performed using electrochemical impedance spectroscopy in a planar, two-electrode arrangement. We found out that the stainless steel was highly corrosion resistant in all the tested fuels while the mild steel exhibited very good corrosion resistance only in the pure alcohol-gasoline blends. However, the mild steel corrosion resistance decreased considerably after contamination, especially in the case of butanol-gasoline blends, and the highest mild steel corrosion rate was measured in the contaminated B85 fuel with 6 vol. % of water having the lowest value of polarization resistance of 128 kcm2. Furthermore, pitting corrosion was observed in the B40 and higher fuels even at short exposure times, and, once being contaminated, butanol-gasoline blends were found to be more aggressive to the mild steel.
