In order to evaluate the suitability of aluminium alloys for engineering applications in Arabian Gulf Water a joint corrosion research program between the University of Petroleum & Minerals (UPM), Dhahran, Saudi Arabia and OFZS, Austria, was initiated in 1978. Considerable interest in aluminium and its alloys, particularly 5000 series, for marine applications has been shown in recent years. Aluminium alloys having low copper and zinc contents and alloys containing Mg have shown good application potentials in marine environments. Recent attempts to improve the corrosion resistance of AI‐Mg alloys by alloy modifications and optimising the corrosion resistance and mechanical properties have met with some success. Several records obtained from OTEC heat exchangers and Aluminium Association desalination plants show promising application potentials of aluminium and certain aluminium alloys. In view of the rapid growth of desalination technology in the Kingdom of Saudi Arabia a great demand has been placed on the understanding of the corrosion behaviour of important engineering materials in local environments, and the need for development of alternate materials. A field test rig was therefore built in co‐operation with CFZS, Austria and installed at the UPM (Dhahran, Saudi Arabia) beach in 1978 for long term corrosion testing. This paper describes the results of a joint test program on the corrosion of aluminium and selected aluminium alloys in Arabian Gulf Water obtained from test rig, and laboratory studies.

“…One of the materials mostly used in heat exchangers is aluminum alloy. Aluminum alloy is one of the major materials used for heat exchangers because of its lower density, excellent resistance to corrosion, and great machinability [12,13]. However, some studies reported on the susceptibility of this alloy to localized corrosion in some media, which can cause its failure [14].…”

In this study, the corrosion behavior of aluminum alloy was investigated in graphene nanoplatelet (GNP) nanofluids prepared with different surfactants. The surfactants include sodium dodecylbenzene sulfonate (SDBS), sodium dodecyl sulfate (SDS), Tween 80, and Gum Arabic (GA). The corrosion properties of the alloy in the different GNP nanofluids were evaluated using potentiodynamic polarization tests at room temperature. The surface morphology of the aluminum alloy was analyzed using a scanning electron microscope coupled with an electron dispersive spectroscopy detector. The experimental results revealed that the addition of surfactants improves the resistance of the aluminum alloy to corrosion in the nanofluid. This was attributed to the adsorption of surfactants on the surface of the alloy to form a protective film layer, which reduces moisture permeability and enhances corrosion inhibition. The addition of GA was found to exhibit the highest inhibition efficiency. This was followed by Tween 80, SDS, and SDBS, which contributes the least inhibition. XRD post-corrosion analysis also reveals the presence of aluminum oxide and aluminum hydroxide phases on the surface of electrodes immersed in all the different GNP nanofluids.
