The Laboratory of Materials and Coatings (LMR) of LNEG is a specialized center in the fields of corrosion, degradation and anticorrosive protection of materials.

Within the physical and chemical characterization of materials and coatings, the following tests can be carried out:

  • Vickers Microhardness*
  • X-Ray Diffraction (XRD) – Identification of crystalline constituents or phases in inorganic materials *
  • Qualitative or semi-quantitative chemical analysis of elements with atomic number> 5 by energy dispersion spectrometry (EDS) associated with scanning electron microscopy (SEM) *
  • Brinell hardness *
  • Rockwell hardness *
  • Vickers hardness *

* Test not included in the scope of accreditation.


Cost upon request.

Deadlines for the service

  • To carry out tests the time limit for submission of a quotation is 24 to 96 hours after request, depending on its extend/complexity;
  • Tests are initiated after acceptance of quotation and reception of samples or as agreed between parts;
  • The report is issued 10 days after the end of the tests. This period may be extended depending on the number of samples tested as well as on the number of tests carried out.
