Nondestructive testing is a vital tool in the effort to ensure the quality of mechanically highly-loaded aero-engine parts. Nondestructive testing methods, such as eddy current and dye penetrant, are used to verify the surface condition of components, this condition greatly affecting operational safety and service life. Yet while these methods will readily detect small cracks, they fail to show the gradual changes in surface topology commonly associated with service wear.
