The expertise of CEIT-IK4 in the development and calibration of customised non destructive testing systems based on electromagnetic techniques can be applied to in-process and production-related quality control of automotive metallic components:

  • 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
