Surface analysis

Thanks to our trained and experienced professional personnel and our modern technology, Horn & Co. is happy to support you in characterising materials and finding the causes of damage. Our analyses can help with the following, for instance, depending on the specific application:

  • identifying minute inclusions, cracks or other faults in a workpiece and analysing their components,
  • inspecting very thin layer systems or minute particles and
  • visualising and assessing the structure of steel, ceramics or shaped fire-resistant products, for instance

Our surface analysis services:

Imaging processes

  • High-resolution images of a surface (structures, inclusions, layer systems, broken areas, cracks) or very small particles at very high zooms using a scanning electron microscope (SEM) or light microscope
  • Visualizing objects in the micro to nanometre range


Determining the elemental composition of a surface

  • Qualitative and semi-quantitative elemental analysis of large surface areas using wavelength dispersive X-ray spectroscopy (WDs)
  • High-resolution qualitative and semi-quantitative analysis in the micrometre range of surfaces using energy-dispersive X-ray spectroscopy (EDS) combination with the scanning electron microscope (SEM),
  • Determining the composition of inclusions, faults or layer systems
  • Determining the elemental distribution of selected surface areas (mapping)
