Technische Universität Berlin seeks a 0.75-time Research Assistant for a DFG-funded project on improving the endurance limit and coatability of Ti-6Al-4V titanium alloys via plasma electrolytic oxidation and shot peening. The role involves optimizing hydroxyapatite coatings, conducting micro-/nanoindentation and fatigue testing, and characterizing coating structure and mechanical performance using advanced microscopy and tomography. The candidate will contribute to theoretical development, publications, and conference presentations, and collaborate closely with production engineering partners. Applicants must hold a Master’s degree in materials science, mechanical engineering, biomedical engineering, or a related field with strong experimental expertise.
