Join us in person or online for an exciting seminar where we will present the innovative advancements of the European project ALCOAT. Learn about the physically informed multiscale simulation model developed by the teams of Prof. Ivan Cole (RMIT, ANU) and Prof. Pablo Ordejón (ICN2) for creating advanced recycled sacrificial coatings.
The ALCOAT project aims to transform steel corrosion prevention using scrap aluminium (s-Al) coatings within a circular economy approach. This research promises numerous potential benefits, including a 60-70% reduction in coating mass, up to 75% cost savings, and significantly lower environmental impacts compared to standard zinc coatings, potentially saving 11.7 megatons of CO2 equivalent annually. While the composition of s-Al varies rendering it problematic for many applications, these impurities may actually enhance its anti-corrosive performance. Our objective is to thoroughly evaluate and identify optimal s-Al compositions by testing under field-like atmospheric conditions. As a key part of the ALCOAT project, we are developing a physically informed multiscale simulation model. This model integrates molecular-scale insights gained through density functional theory (DFT) with continuum-scale finite element simulations, validated against experimental data. Our approach indicates the significant role of trace metals in disrupting the protective oxide layer in localized areas, thereby reducing the passivation of sacrificial coatings, while ensuring a low corrosion rate, and minimising the risk of hydrogen embrittlement. Applications of this research can improve corrosion protection of both exposed structures (wind turbines, ships, etc.) and steel sheet (automotive panels, building facades, and home appliances).
ALCOAT has received funding from the EU Research Fund for Coal & Steel (RFCS).
