Home | Test | Micrography/Metallography



By looking very closely at the structure and surface layers of the material with an optical microscope, we can make an analysis of the internal purity and detect possible errors in the material. This can be interesting in case of damage.

Can be applied to:

metals, composites, coatings, plastics, 3D prints

Test procedure standards:

EN ISO 945

Test procedure:

A sample is processed into small pieces, which are then embedded, polished and etched. The polished samples are placed under the microscope and the enlarged structure is photographed. These are called micrographs, which are then analysed by our material experts and described in a report.

Lead time:

 5 business days

All tests – composites – metals – plastics – coatings – adhesives – 3D prints
