Aluminum alloys with silicon and magnesium, by potentiodynamic polarization tests and Electrochemical Impedance Spectroscopy in bioethanol solution (92º - 96º), room temperature and pH 6.5, evaluating the effects of the ...

Nowadays, biofuels represent a large part of renewable energies destined to substitute fossil fuels, and to reduce the negative impact on the environment. Bioethanol is obtained by alcoholic fermentation, and is used pure ...

Hypereutectic Al-Si alloys can be used in applications that require high wear resistance. Such wear resistance is achieved by the presence of hard primary silicon particles, allied to the formation of Mg2 Si intermetallic ...

The 7XXX series aluminum alloys are widely used by the aeronautical and automotive industries due to their lower density and better mechanical performance. Adding alloying elements, such as zinc, magnesium, copper, silicon ...
