Magnetic Particle Testing (MPI)
At F AND E NDT (PTY) LTD, we harness the power of Magnetic Particle Testing (MPI) to provide a comprehensive solution for detecting surface and slightly subsurface discontinuities in ferromagnetic materials. This method is vital in ensuring the structural integrity of materials such as iron, nickel, cobalt, and their alloys.
MPI operates on the principle of magnetization. The specimen under examination is magnetized to generate magnetic lines of force, or flux, within the material. When these lines of force encounter a discontinuity, like a crack, secondary magnetic poles form at the crack's faces. At the surface of the metal, these secondary magnetic fields can be revealed by applying magnetic particles in either a powder form or a liquid suspension.
To heighten visibility, magnetic particles may be either black or coated with a fluorescent dye. These particles are irresistibly drawn to the flux leakage, clustering around the flaw, and rendering it prominently visible. For optimal results, it is critical that the magnetic flux lines intersect the flaw at right angles, resulting in maximum flux leakage. The choice of magnetizing technique is carefully selected to ensure comprehensive coverage, often requiring the utilization of multiple techniques.
