| Popis: | 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 for production industries and handling biofuel, it is crucial the effectiveness of materials against corrosion, so in recent years the increase is denoted in corrosion studies of metallic alloys applied in these industries. The aim of this work is to study the corrosion behavior of aluminum-magnesium alloys, using potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS) tests in ethanol (99.5% v/v) at room temperature, evaluating the effects of microstructure and percentage of magnesium addition. Furthermore, the mechanisms involved in corrosion are proposed, compared to the different theories suggested by other authors. |
