Guest researcher strengthens WOT team

Since the beginning of April, we have been welcoming a guest scientist. Mehri Hashemzadeh is doing her doctorate at the Isfahan University of Technology on the influence of titanium-based electrolyte additives in the plasma electrolytic oxidation (PEO) of aluminium and is spending six months as a visiting scientist 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. These strike the substrate surface from the electrolyte and create a ceramic protective layer. 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.

Ms Hashemzadeh will therefore be working on methods of electrolyte development and materials analysis 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.
