Resumen:
Technological changes driven to solve the energy problems existing in the world today,offer a key opportunity for sciences related to the selection of materials. Specifically forproduction industries and handling biofuel, it is crucial the effectiveness of materialsagainst corrosion, so in recent years the increase is denoted in corrosion studies of metallicalloys applied in these industries. The aim of this work is to study the corrosion behavior ofaluminum-magnesium alloys, using potentiodynamic polarization and ElectrochemicalImpedance Spectroscopy (EIS) tests in ethanol (99.5% v/v) at room temperature, evaluatingthe effects of microstructure and percentage of magnesium addition. Furthermore, themechanisms involved in corrosion are proposed, compared to the different theoriessuggested by other authors.
