  • Publication number: 20030193331
    Abstract: A method for in-situ eddy current inspection of at least one coated component includes applying a drive pulse at a measurement position on an outer surface of the coated component, while the coated component is installed in an operational environment of the coated component. The coated component includes a base metal and a coating disposed on the base metal. The method further includes receiving a response signal from the coated component, comparing the response signal with a reference signal to obtain a compared signal, analyzing the compared signal for crack detection, and determining whether a crack near the measurement position has penetrated into the base metal, if the presence of the crack in the coating is indicated.

  • Publication number: 20020190724
    Abstract: A pulsed eddy current two-dimensional sensor array probe for electrically conducting component inspection includes a drive coil disposed adjacent to a structure under inspection, a pulse generator connected to the drive coil and operable to energize in a pulsed manner the drive coil to transmit transient electromagnetic flux into the structure under inspection, and an array of sensors arranged in a two-dimensional array and substantially surrounded by the drive coil and operable to sense and generate output signals from the transient electromagnetic flux in the structure under inspection.
