Visiting scientist strengthens WOT team
Since the beginning of April, we have been pleased to welcome a guest scientist. Ms Mehri Hashemzadeh is doing her doctorate at the Technical University of Isfahan on the influence of titanium-based electrolyte additives in the plasma electrolytic oxidation (PEO) of aluminium and is spending six months as a guest researcher at our professorship with a scholarship from her home country Iran.
PEO is a wet-chemical surface treatment process in which metallic materials undergo a strong polarisation within an aqueous electrolyte, which enables the initiation of plasma electrolytic spark discharges. Starting from the electrolyte, these strike the substrate surface and create a ceramic protective layer there. Such PEO coatings are extremely wear-resistant and offer excellent corrosion protection. However, the process has a negative effect on the fatigue strength of the treated components.
Therefore, Ms Hashemzadeh will be working on methods of electrolyte development and materials analytics as part of preliminary work for a DFG project on fatigue-resistant PEO coatings. We enjoy the cultural exchange and look forward to innovative results.
