6 Advantages of Wet Suspension Magnetic Particle Testing

 · Magnetic particle testing (MPI) is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys.. This testing method uses very fine iron oxide particles to find small discontinuities. These particles come in two forms: dry powder or wet suspension.

Dry Particle Inspection - nde-ed.org

Dry particle inspection is well suited for the inspections conducted on rough surfaces. When an electromagnetic yoke is used, the AC or half wave DC current creates a pulsating magnetic field that provides mobility to the powder. The primary applications for dry powders are unground welds and rough as-cast surfaces.
