  • Method for non-destructively assessing the condition of a turbine blade using eddy current probes inserted within cooling holes
    Patent number: 5140264
    Abstract: The present invention provides a method and apparatus for performing nondestructive material assessment of service exposed combustion turbine blades. According to the invention, the testing is accomplished by inserting eddy current (EC) probes into the blade's cooling holes, and evaluating the eddy current response of the blade. The eddy current probes are preferably coupled together in a differential mode. The measured response is then compared with a previously determined response corresponding with a known material condition. An assessment of the blade is made on the basis of this comparison.
