CORROSION RESISTANCE OF ALUMINUM ALLOYS

Corrosion of Aluminium highlights the practical and general aspects of the corrosion of aluminium alloys with many illustrations and references. In addition to that, the first chapter allows the reader who is not very familiar with aluminium to understand the metallurgical, chemical and physical features of the aluminium alloys. The author Christian Vargel, has adopted a practitioner approach, based on the expertise and experience gained from a 40 year career in aluminium corrosion This approach is most suitable for assessing the corrosion resistance of aluminium- an assessment which is one of the main conditions for the development of many uses of aluminium in transport, construction, power transmission etc. He was chief engineer at Pechiney which was the European leader of wrought, extruded and cast aluminium products — where he primarily focused on corrosion of aluminium alloys, from a practical perspective. He surveyed and appraised numerous cases of in-service aluminium corrosion: building, transport, territory equipment, electrical and applications, and renewable energies such as solar, desalination and OTEC.

Corrosion is the chemical reaction of a metal, in this case aluminum, with its environment, which leads to the deterioration of the properties of metals, aluminum in this case.

Description

Corrosion fatigue tests were performed on three cast aluminium alloys in engine coolant using a revolving bending test apparatus. A decrease in the bearable load is detected for the tests under corrosive conditions compared to standard fatigue testing in air. The surface condition of the test specimens showed a remarkable influence, whereby specimens with a machined surface failed earlier than those with as-cast surface condition. Electrochemical noise measurements could be used to detect the early stages of failure. To evaluate the load of high performance engine parts all components of the load population have to be known and their influence on the lifetime has to be investigated 1.

Corrosion of Aluminium

Based on long-term tests of aluminum alloys in seawater of various climatic zones from the Arctic to the tropics, the peculiarities of their corrosion behavior are revealed. In contrast to other alloys, hydrogen sulfide has a beneficial effect on their corrosion resistance due to the passivation. However, deep in the Black Sea, the alloys, which are susceptible to structural types of corrosion, were subjected to strong exfoliation corrosion, because hydrogen sulfide excluded fouling with microorganisms that inhibits exfoliation corrosion. Alloys of the Al-Mg system exhibit the highest corrosion resistance in seawater. Alloying with scandium and thermomechanical treatment make possible further simultaneous improvement of mechanical properties and corrosion resistance.

Scientists of the United States National Bureau of Standards have found that some aluminium alloys can resist corrosion in either a marine or inland atmosphere for at least 20 years. Reinhart and G. Ellinger, of the Bureau's staff, for the Navy Bureau of Aeronautics.

Aluminum alloys are incredibly versatile, sturdy, and reliable. For this reason, they are very sought-after in engineering, construction, and automotive applications, making for one of the most widespread metal materials, alongside steel. Keep reading to learn more about the qualities, applications, and unique characteristics of aluminum alloys. While aluminum presents some amazing properties as a pure element, it might not be strong enough for the high-durability purpose. For this reason, it can be combined with other elements in order to form alloys, which are exponentially more durable and suitable for industrial applications.

Marine Corrosion and Protection of Aluminum Alloys According to Their Composition and Structure

The spallation of aluminum, chromium, and iron oxide scales is a chronic problem that critically impacts technological applications like aerospace, power plant operation, catalysis, petrochemical industry, and the fabrication of composite materials. The presence of interfacial impurities, mainly sulfur, has been reported to accelerate spallation, thereby promoting the high-temperature corrosion of metals and alloys. The precise mechanism for sulfur-induced destruction of oxides, however, is ambiguous.

A commercial aluminum alloy was subjected to severe plastic deformation through equal channel angular pressing ECAP. The effects of scan rate and NaCl concentration on the alloy susceptibility to corrosion were also studied. The results obtained were compared with those of the nonpressed alloy. ECAP leads to an intensive grain refinement accompanied by an increased dislocation density.
