What is Magnetic Particle Inspection?

Magnetic Particle Inspection (or MPI) is used to detect surface defects in ferromagnetic (or magnetic) materials. A magnetic field is generated inside the component and a magnetic particle powder is applied. The magnetic flux leaks through any defects and attracts the particles, highlighting any defects.

What is MPI used to detect?

MPI is normally used to detect defects in surfaces, such as toe cracks and crater cracks. It also allows the identification of areas of porosity. It is a portable, simple method for use on castings, shafts, and welds. It gives instant results and can detect defects up to 2mm below the surface.

What limitations does MPI have?

This method requires surfaces to be clean before testing commences. It also can require a power source and uses flammable liquids, so might not be suitable for certain areas on-site. MPI cannot be used on non-ferromagnetic materials.
