CASR Inspection Methods

Magnetic Particle Testing

A magnetic field is established in a component made from ferromagnetic material. The magnetic lines of force or flux travel through the material, and exit and reenter the material at the poles. Defects such as cracks or voids are filled with air that cannot support as much flux, and force some of the flux outside of the part. Magnetic particles distributed over the component will be attracted to areas of flux leakage and produce a visible indication.
