It is essential for the development of new coatings, just as for the control of pieces from proven technologies, to be able to carry out characterizations in order to qualify and quantify their mechanical, physical and chemical properties.

Since 2009, CITRA has acquired some equipments linked to its activities: first by investing in characterization techniques adapted to the needs of expertise from the industrial sector and, secondly, by having access to research material thanks to its partnerships with the SPCTS laboratory and the ENSIL-ENSCI engineering school.

Customed Characterization

Certified ISO 9001, CITRA offers services adapted to the technical needs of its customers. With this in mind, we undertake to carry out “custom” characterization based on personalized needs or cross-sectional characterizations integrated into longer-term projects, guaranteeing the best delays.

In addition to the ressources mentioned previously, the implementation of CITRA inside the premises of ENSIL-ENSCI gives it access to the following types of characterization:

  • Nanoindentation
  • Laser granulometry
  • Brookfield Viscometer
  • Helium porosimeter
  • Scratch test

CITRA also has a panel of sample preparation techniques allowing it to adapt them according to customer needs.

Field Emission Scanning Electron Microscope (MEB FEG)

In the domain of surface treatments, microscopic observation is an essential element of analysis for the understanding and the good realization of coatings. In order to ensure an optimum service to its customers and partners, CITRA has chosen to invest in a Karl Zeiss SUPRA 40 field emission scanning electron microscopy (SEM) system. It technical specifications ensure a very interesting versatility since it allows classical observations up to high resolution observations (magnification x 500 000). Equipped with an EDS probe, this equipment also makes it possible to perform very localized or global elemental analysis. Thanks to this equipment, CITRA has a better control of its coatings and is able to offer complete services (coating + characterization) or characterization expertise only.

SEM characterizations offered:

  • Visual observations
  • Micronic and nanometric measurements
  • Structural and topographic analysis
  • Chemical contrast analysis (BSD)
  • Chimical mapping
  • Determination of the porosity rate in crossection
  • Process expertise
