Magnetic particle testing

It is possible to confirm invisible scratches! Suitable for detecting cracks-like scratches that exist near the surface.

"Magnetic particle testing" can only be applied to ferromagnetic materials that are attracted to magnets. When using the equipment to magnetize a ferromagnetic material (test specimen), a magnetic flow called magnetic flux is generated within it. If there are cracks or other defects on the surface or near-surface of the test specimen, the magnetic flux will leak into the surface space due to the defects, forming small magnets. When very fine iron powder (magnetic powder) that has been colored is sprinkled on that area, the magnetic powder adheres to the defect, and the adhered magnetic powder becomes a magnet, allowing the magnetic powder to stack together and form patterns, which is used to detect the defects. [Features] ■ Can only be applied to ferromagnetic materials that are attracted to magnets ■ Utilizes the adhesion of magnetic powder to the defect, where the adhered magnetic powder becomes a magnet, allowing the magnetic powder to stack together and form patterns to detect defects ■ The aggregation of magnetic powder creates patterns that are enlarged compared to the actual defects ■ Allows for the confirmation of narrow, invisible defects *For more details, please refer to the PDF document or feel free to contact us.
