  Principle
  A constant force is applied on the sample surface with an indenter – typically a Vickers pyramid – in order to create a surface deformation. Then the hardness of the test sample is determined from the load needed to create the deformation and the dimensions of the permanent deformation.
  Hv = P/S
  Where P is the load applied on the sample surface (kgf) and S the indentation surface (mm²)

  FRACTOGRAPHIC INVESTIGATION: Understanding and determining the origin of a failure
  The failure of a material, part or structure can lead to many economic consequences for an industrialist. When a failure occurs, it is important to identify its nature and origin in order to set up corrective actions.
  The laboratory’s skills in failure analysis allow us to carry out a full investigation using our high-performance test facilities. Our long-standing experience allows us to highlight (...)

  MECHANICAL CHARACTERIZATION: Microstructure, hardness of materials, abrasion resistance, etc.
  Mechanx²ical tests are used to determine the behavior of materials and identify their mechanical characteristics. These characterizations are used to ensure that the structure of the material will be tailored to the use of the final part and thus overcome any possible defects or breakages in operation.
  The laboratory’s equipment allows us to determine the following characteristics:
  • Determination (...)
