Mediums for Magnetic particles Testing

Magnetic particles Testing (MT) allows for quick and reliable detection of any surface defects in ferromagnetic materials, caused by cracks, heterogeneous structure, foreign insertations and material discontinuities. This method is applied when detecting flaws at (the so-called "open flaws") or near ("closed flaws") the surface of the test piece. It may be used at elements with thin galvanic coatings.

Magnetic particles testing should be carried out with help of magnetizing devices - magnetic defectoscopes.
In order to visualize the defects ferromagnetic particles are used. When using fluorescent particles one will have to take advantage of UV-lamps, too.

For quality control of inspections that are being carried out, test blocks should be used - available by KALLA Ltd.
