What is the magnetic particle inspection?
Magnetic particle inspection acc. to DIN EN ISO 9934
From practice: Magnetic Particle Inspection fluorescent
There are various types of detection media: a suspension of coloured (including black) or fluorescent particles in a carrier fluid (based on water or oil), or dry powders. Fluorescent media usually gives the highest sensitiviy.
The test area can be sprayed with a dry magnetic powder, or the workpiece can be dipped into a container in which the particles are kept afloat by air whirling (eddy pot procedure). The dry testing is recommendable where a wetting of the surface must be avoided, or with the examination of hot parts.
The magnetic powder is suspended in a carrier fluid. The particle size of the powder is smaller so that smaller discontinuities may be detected.
