OUR MISSION

  • We achieve innovations in joining technologies & corrosion management

  • by microstructural and interfacial design

  • of nano-structured materials and their assemblies

  • in close-collaboration with academia and industry.

OUR EXPERTISE

Our laboratory possesses strong competencies in the fields of joining (e.g. brazing, soldering, diffusion bonding, alloy design), corrosion, electrochemistry, functional and passive oxide films, nano-materials and nano-structured coatings.

Sustainable materials and technologies for joining and corrosion management are developed in close-collaboration with key industries in the fields of aerospace and automotive technologies, civil engineering, machine tooling, power generation, medical implants, packaging, microelectronics and sensing devices.

We are a national competence centre for the investigation of corrosion failures and the development of corrosion prevention strategies. On a daily basis, we offer high-end services to exigent industrial needs in the fields of corrosion, joining, electrochemistry, surface analysis and materials engineering.

OUR RESEARCH

Our research aims at fundamental knowledge and engineering know-how for tailoring reactions and microstructural evolutions at solid-solid, solid-liquid and solid-gas interfaces. To this end, smart experiments are combined with model descriptions for disclosing the thermodynamics and kinetics of reactions and phase formations at free surfaces and at buried interfaces under varying operating conditions (e.g. at elevated temperatures, in complex physiological media or reactive gas atmospheres and/or under mechanical loading conditions).

Technology transfer of our R&D into innovative and sustainable products and technologies necessitates model predictions and experimental verifications of the performance of materials and their assemblies under varying operating conditions. Hence multi-scale modelling approaches (combining e.g. density functional theory, molecular dynamics, Monte-Carlo, finite elements and CALPHAD methods) are indispensable research tools targeting at:

  • Development of thermodynamic and kinetic databases of alloys, oxides and oxyhydroxides with relevance to joining, corrosion and materials manufacturing.
  • Model predictions of melting behaviors and interfacial reactions in nano-structured coatings and nano-foils for low-temperature joining applications.
  • Life-time predictions of material joints and medical implants in extreme environments (e.g. at high-T, in complex physiological media, under thermo-mechanical loading).
