On-line/Off-line manufacturing quality control through non-destructive testing techniques

 Description

The expertise of Ceit 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 manufacturing 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.

 Capabilities

• 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
