Combined Corrosion and Wear of Aluminium Alloy 7075-T6

The aluminium alloy 7075-T6 is widely used in engineering. In some applications, like slurry transport, corrosion and abrasion occur simultaneously, resulting in early material failure. In the present work, we investigated the combined effect of corrosion and wear on the aluminium alloy 7075-T6. We performed two series of wear experiments to...

Protective film formation on AA2024-T3 aluminum alloy by leaching of lithium carbonate from an organic coating

An investigation into corrosion inhibition properties of a primer coating containing lithium carbonate as corrosion inhibitive pigment for AA2024 aluminum alloy was conducted. It was found that, during neutral salt spray exposure, a protective film of about 0.2 to 1.5 ?m thickness formed within the area where an artificial defect was introduced...

Aerosol-based Emission, Solvent Degradation, and Corrosion in Post Combustion CO2 Capture

Global greenhouse gas emissions, especially of CO2, have been increasing tremendously over the past century. This is known to cause not only an increase of temperature, but also a change in our climate. Along with a shift to renewable sources of energy, Carbon Capture and Storage is necessary to mitigate climate change. Power plants are the...

Multiple action self-healing coatings for the corrosion protection of metals (abstract)

The influence of deformation on the product performance of pre-coated packaging steels

Recent developments in various countries have led to the development of new types of polymer coated packaging steel. These materials behave differently in production and end use and are therefore subject of extensive studies. The aim of this research is to understand the influence of deformation of pre-coated packaging steel sheet on real can...

The role of magnesium in the electrochemical behaviour of 5XXX aluminium-magnesium alloys

An investigation concerning the effects of magnesium on the intergranular corrosion susceptibility of AA5XXX aluminium alloys was carried out. In the present work, magnesium is found to be highly mobile in the bulk metal as well as in the aluminium oxide. This mobility is also found to be dependent on the temperature and bulk magnesium...

Cr(VI) and Cr(III)-Based Conversion Coatings on Zinc

With the aims of understanding the protective mechanism of chromate conversion coatings and developing alternatives to chromate treatments, the physical natures and corrosion properties of Cr(VI) and Cr(III) treated zinc have been investigated in this work. The Cr(VI) treatments were carried out in dichromate and sulfuric acid solution with...
