CEIT-IK4 has a broad expertise in the development and calibration of customised non destructive testing systems based on electromagnetic techniques. Our large experience in aspects such as the nondestructive quality control of aeronautical metallic components can be applied to:

  • Grinding burns and grinding process control.
  • Residual stresses (created during the manufacturing process or by cold-working processes such as shot peening).
  • Control of thermal treatments, hardness gradients.
  • Cracks and pores, surface defects through Cr-coating.
  • Microstructural characterization, retained austenite.


  • Nondestructive

    Development and calibration of customized sensors and customized electronic

    Magnetic Barkhausen Noise measurements or BNA analysis

    Magnetic flux leakage measurements

    Eddy current measurements: HOCKING Vector 2d with various test probes and Impedance analyzers (FLUKE, HIOKI)

  • Destructive

    Microstructural characterisation: Optical and electronic microscopy : FEG-SEM, EBSD, STEM, FIB

    Mechanical test at local scale

    Micro and nanohardness

    X-ray diffraction: Residual stresses
