The Bundesanstalt für Materialforschung und -prüfung (BAM) is a materials research organization in Germany. Our mission is to ensure safety in technology and chemistry. We perform research and testing in materials science, materials engineering and chemistry to improve the safety of products and processes. At BAM we do research that matters. Our work covers a broad array of topics in the focus areas of energy, infrastructure, environment, materials, and analytical sciences.

We are looking for talented people to join us.

Your responsibilities include:

Work in a research project on the effect of sulfide and oxygen on the formation and stability of protective surface layers on steel reinforcement in concretes with sulfide-containing pore solution in collaboration with RWTH Aachen University:

  • Design and production of sulfide-containing binders based on Portland cement, ground granulated blast furnace slag and hard coal ash
  • Microstructural analyses of the hardened binder pastes and comparison with the results of thermodynamic-geochemical modelling of the phase assemblages
  • Electrochemical analyses of the passivation and corrosion initiation of steel in sulfide-containing solutions, with and without the presence of chlorides and/or oxygen, in electrochemical cells
  • Characterization of the steel surfaces using scanning electron microscopy (SEM) and time-of-flight secondary ion mass spectrometry (ToF-SIMS)
  • Development of a model of the passivation and corrosion initiation of steel reinforcement in concretes with sulfide-containing pore solution and, based on this, re-evaluation of traditional criteria for the assessment of the corrosion risk of steel reinforcement in concrete
  • Documentation and publication of the results

Your qualifications:

  • Successful scientific degree (Master / Diploma) in materials science, chemistry, applied geosciences, mineralogy, building materials engineering, or equivalent academic studies
  • Theoretical knowledge of metal corrosion and practical experience with standard electrochemical techniques for the analysis of corrosion phenomena (e.g., linear polarization method, galvanostatic pulse measurements)
  • Theoretical and practical knowledge of X-ray powder diffraction, thermal analyses (TG/DSC), pore structure analysis, thermodynamic modelling software, SEM and/or ToF-SIMS are advantageous
  • Very good command of English (written and spoken); good command of German (written and spoken) is advantageous
  • Good publication and presentation skills
  • Goal-oriented and structured way of working, initiative / commitment, ability to work in a Team / willingness to cooperate, willingness to learn, flexibility

We offer:

  • Interdisciplinary research at the interface of politics, economics and society
  • Work in national and international networks with universities, research institutes and industrial companies
  • Outstanding facilities and infrastructure
  • Flexible working hours and mobile working
