Friction stir welding (FSW) is a solid-state joining method that suitable for dissimilar materials such as aluminum and steel due to its comparatively low process temperatures. Such hybrid joints are of great interest in view lightweight construction efforts various industrial sectors transportation. As the combination different metals structures may cause corrosion problems area because format...

We investigated the galvanic corrosion behavior of aluminum alloy in contact with carbon steel during accelerated testing by evaluating current and morphology coupled specimen. Electrochemical polarization curve was acquired before after testing, only detected for dissolution. Aluminum next to more severely corroded than remote aluminum. Corrosion also observed steel, although its dissolution n...

The galvanic couple AA2024/Carbon Fiber Reinforced Polymer (CFRP) has been studied numerically and experimentally in a dynamic electrolyte droplet. As an electrolyte, NaCl droplet (0.6 M initial concentration) was used at controlled temperature (24.5°C) relative humidity (83.5%). evaporation of the monitored for 24 hours using Scanning Kelvin Probe (SKP), simulating atmospheric corrosion phenom...

THE GALVANIC CELL The major corrosion concern in the water works industry is “galvanic” corrosion. Galvanic corrosion takes place due to current flow in a “galvanic cell” which is defined as (1) two dissimilar metals, an anode and a cathode, (2) in electrical contact with each other and (3) a common electrolyte. A galvanic cell is produced when the pipeline components come in contact with the s...

At present, there is an ongoing search for approaches toward the storage of energy from intermittent renewable sources like wind and solar. Flow batteries have gained attention due to their potential viability for inexpensive storage of large amounts of energy. While the quinone/hydroquinone redox couple is a widely studied redox pair, its application in energy storage has not been widely explo...

Traditional electrochemical techniques, such as linear polarization resistance (Rp), and electrochemical impedance spectroscopy (EIS), cannot be applied to gilded bronzes, as it may not be possible to interpret the results obtained due to the bimetallic nature of the studied material. The measurement of the macrocouple current generated by the gold/bronze galvanic couple can be used as an indic...
