Evaluation of corrosion resistance of aluminum-based alloys in bioethanol produced in Misiones
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 ...
Influence of chromate, molybdate and tungstate on pit formation in chloride medium
It has been characterized and evaluated the 2024-T351 and 7050-T7451 aluminum alloys pitting corrosion in naturally aerated chloride aqueous solutions containing chromate, molybdate and tungstate. It has been carried out ...
Influence of the heat treatment in the electrochemical corrosion of Al-Zn-Mg alloys
The localized corrosion of Al-(5.03%)Zn-(1.67%)Mg-(0.23%)Cu alloys and high purity Al has been studied using electrochemical techniques, optical microscopy, SEM and EDX. The samples were previously submitted to different ...
Correlation between microstructure and corrosion behavior of two Al-Fe-Si alloys
In this work, the corrosion behavior of the AA4006 alloy made by the twin roll caster process was evaluated using electrochemical impedance spectroscopy (EIS), anodic potentiodynamic polarization curves, and scanning ...
The role of coarse intermetallics in the localized corrosion behaviour of AA 2024-T3 in low concentrated chloride media
Aluminium alloy (AA) 2024-T3 is an important engineering material due to its widespread use in the aerospace industry. However, it is very prone to localized corrosion attack in chloride containing media, which has been ...
Suitability of carbon fiber-reinforced polymers as power cable cores: Galvanic corrosion and thermal stability evaluation
(Elsevier B.V., 2015-01-01)
The increasing demand for electrical energy and the difficulties involved in installing new transmission lines presents a global challenge. Transmission line cables need to conduct more current, which creates the problem ...
