Lifetime Concepts for Hydrogen Applications


  • Assessment of damage mechanisms in components; Development of corrective measures
  • Providing evidence of hydrogen brittleness
  • Selection, qualification and characterization of materials for hydrogen applications
  • Residual stress optimization to avoid cold crack formation of welding joins
  • Assistance in avoiding hydrogen brittleness in additive manufacturing processes
  • Optimization of degassing heat treatments, e.g. after galvanic coating
  • Optimization of welding and heat treatment processes
  • Development of new protective layers against hydrogen
  • Suitability of lubricants in rolling bearings, key term: “white etching cracks”
  • Support of complex development projects in the area of hydrogen technology, e.g. Power-to-Gas (P2G) and hydrogen as an energy carrier


Hydrogen embrittlement in metals


Atomic hydrogen is able to significantly reduce the ductility of metallic raw materials. This can lead to the expected malfunction of components and is generally referred to...
