Your tasks

You focus on developing your PhD project Mechano-corrosive properties of PBF-LB manufactured biodegradable Mg and Zn alloys. A combination of dynamic mechanical loading and corrosive environment is imposed on a metallic device upon implantation. While the influence of both factors is typically studied and tested separately, their inevitable combination at implantation site may lead to unexpected and premature implant failure due to stress corrosion cracking, corrosion fatigue and tribo-corrosion. Understanding cooperative effects of mechanically assisted corrosion of the Mg and Zn alloys (additively manufactured at Uppsala University) will be the focus of this PhD project. The objectives of this work are to optimize an experimental setup for simultaneous tension/compression testing and localized corrosion measurements, including monitoring of local pH and dissolved hydrogen and oxygen concentrations at metal-electrolyte interface; gain understanding of the factors influencing the initiation and propagation of localized corrosion and associated mechanically assisted corrosion.



Research stays are planned at: Uppsala Universitet, Sweden, and Quintus Technologies AB, Västerås, Sweden



Supervisors: Dr. Sviatlana Lamaka, Prof. Cecilia Persson, Prof. Mikhail Zheludkevich
