Testing Services

Material characterization

  • Topography: characterization of structures and defects: SEM, confocal white light microscopy, AFM
  • Coating analysis: Thickness, cross-section, layer sequence: FIB, SEM, TEM, ellipsometry
  • Compound distribution studies on surfaces: Raman
  • Chemical characterization (ISO 10993-18): Influence of production, storage and degradation, etc. XPS, FTIR, Raman, SNMS
  • Surface wettability: contact angle measurement
  • Thermal sample characteristics: DMA, DSC

Mechanical testing

  • Fatigue testing of dental implants (ISO 14801)
  • Static material and component testing (tension, compression, bending, shear strain, peeling)
  • Corrosion tests
  • Corrosion resistance (ISO 10993-15, ASTM F 2129)
  • Degradation products from metals and alloys (DIN EN ISO 10993-15)
