  • Nondestructive profiling of articles including ceramic coatings on conductive substrates
    Patent number: 11774232
    Abstract: A method may include positioning an eddy current probe proximate to a coated portion of an article. The coated portion of the article includes a conductive substrate and a ceramic coating overlying the conductive substrate. The method includes generating, using the eddy current probe, a first primary magnetic field to induce eddy currents in the coated portion of the article and measuring, using the eddy current probe, a strength of a first secondary magnetic field created by the eddy currents in the coated portion of the article to obtain a first secondary magnetic field measurement. The method includes determining, by a computing device, one or more properties or one or more changes in properties of the article based on the first secondary magnetic field measurement.
