Magnetic Particle Inspection
Magnetic Particle Inspection is used to find flaws in ferromagnetic materials, such as steel and iron. When there is a flaw [like a crack] at or near the surface of the material being tested, the magnetic field exaggerates the flaws and makes them plainly visible. Fine iron particles are applied to the area under examination. The iron particles can be wet or dry, and can even be suspended in a colored or fluorescent liquid. This technique is primarily used for surface breaking flaws, but it can also be used to detect sub-surface flaws. The deeper the flaw, the less effective this method becomes.
Liquid Penetration Inspection
Liquid Penetration Inspection is a technique used to reveal surface breaking flaws. A liquid penetrant with a colored or fluorescent dye is applied and allowed to sink into surface flaws. After a span of time, the liquid penetrant is removed and a developer applied. The developer acts like a blotter by drawing the penetrant out of the flaws to reveal cracks in the surface. Color contrast penetrants are checked against a bright white light, while fluorescent penetrants need to be check in dark conditions with the use of a black light. This technique can be used on any solid material.
