Surface characterisation

Determination of surface topography, hardness and local chemical composition

  • Non-destructive determination of surface topography and roughness
  • Determination of the surface hardness
  • EDX analysis of surfaces or analysis of surface contaminations

Surface topography of a rough surface

Our Services

  • Roughness measurement according to different standards (e.g. ISO 25178)
  • Topography measurement and documentation of surface changes due to forming processes, abrasive surface treatment or corrosion attack
  • Contour and shape analysis of smaller components (2D or also 3D)
  • Determination of surface hardness according to Vickers (EN 6507)
  • Detection of surface defects
  • Energy dispersive X-ray spectroscopy of metallic surfaces

Evaluation of surface defects
