ABSTRACT:
A non-destructive method of detecting and measuring machining induced surface defects on gas turbine engine components is provided. In an exemplary embodiment, the method includes positioning an evanescent microwave microscope probe adjacent a turbine component surface, and scanning the turbine component surface by moving at least one of the evanescent microwave microscope probe and the component surface in an x-y plane while maintaining a predetermined distance between the probe and the component surface constant.
