Collection: Wet Method Nonfluorescent Magnetic Particles

Wet Method Nonfluorescent Magnetic Particle Inspection (MPI) is a non-destructive testing (NDT) technique used to detect surface and slightly subsurface discontinuities, such as cracks, in ferromagnetic materials. 

Wet Method

  1. Medium: The wet method uses a liquid carrier (usually water or oil) to suspend fine magnetic particles.
  2. Advantages:
    • The liquid helps carry and spread the magnetic particles evenly over the part being inspected.
    • It allows better sensitivity for detecting smaller defects, as the particles can flow easily into fine cracks or defects.
    • Can be applied more effectively on complex geometries

Nonfluorescent

  • Particle Type: Nonfluorescent particles are visible under regular white light, as opposed to fluorescent particles that require UV light.
  • Appearance: Nonfluorescent particles typically appear as black or dark-colored against the background, making them visible to the naked eye under normal lighting conditions.
