The service
- Magnetic Remanence Method (MRM) allows
detection of ferromagnetic inclusions in non-ferromagnetic
surrounding (i.e. gas turbine engine discs)
- The MRM process is a cost effective method of
determining the mass and location of ferrous inclusions
- Maximum sensitiveness of MRM is the detection
of 10mg, 100mm subsurface
- Low Frequency Eddy Current Testing (LFEC)
using SQUIDs or fluxgates allows detection of
cracks, voids and isolating inclusions deep below
the material surface (e.g. 5mm depth in nickel-based
alloy)
- Thermoelectric Method with Magnetic
Readout (TEM) allows detection of material
inhomogenities like segregations as as zones with
local overheating and fatigued regions
- The TEM method can be used to detect overheating
zones on the surface of a workpiece in which the
material phase changes have occured (e.g. by a
damaged tool) |
