Galvanic corrosion of zamak was evaluated in alcohol fuel and in some alcoholic solutions that contained
ionic impurities. Also, the effect of corrosive process on the quality parameters of ethanol was investigated.
The results showed that corrosion of zamak mainly occurred in solutions with high levels of water and
impurities. After the assays, the increasing of both pH and conductivity of the alcohols was observed.
Therefore, the results showed that the contact between zamak and some materials must be avoided and the
quality control of alcohol fuel must be assured as a way of avoiding damages on engines and storagetransportation
fuels systems.
