    摘要： A system (10) and method for monitoring a laser shock peening process includes a sensor (14) connected to a controller (16). The controller (16) includes an input (36, 40) and a processor (38). The input (36, 40) is connected to the sensor (14) to receive a signal indicative of a laser shock event at a workpiece (20). The processor (38) is connected to the input (36, 40) and is configured to determine a time-of-flight (48) of residual energy associated with the laser shock event from the workpiece (20) to the sensor (14) and determine peen quality from the time-of-flight of the residual energy.

    摘要： The present invention is a method for repairing a TBC ceramic top coat in local regions that have experienced a mechanical or thermally-induced spallation event leaving the underlying bond coat intact. A novel combination of groove design (i.e. spacing, pattern and depth) and laser-surface incident angles fabricated into the remaining bond coat is used to achieve spallation resistance equal to or greater than baseline after applying and maintaining a TBC ceramic patch to the localized areas of spallation. The method is particularly useful, but not limited to, repair of coating systems comprised of physical vapor deposited (PVD) ceramic top coats. In a preferred embodiment, the method of the present invention comprises (1) cleaning the exposed spalled region, (2) treating a limited portion of the bond coat by a grooving process with two linear arrays of equally spaced grooves intersecting at a preselected angle so as to texture the surface, and (3) depositing a ceramic material on the surface of the spalled / textured portion of the bond layer. The grooving process is accomplished with a high energy beam.

    摘要： A method and system (14) for monitoring laser shock peening of a work piece (18). A line spectrum is obtained from radiation emitted by a plasma (32) produced by a laser shock peening process. The shape of the line spectrum about its emission peak is compared to a defined line shape to verify proper operation of the laser shock peening process. The line shape may be a Lorentzian line shape corresponding to a desired line shape. The line shape may a Gaussian line shape corresponding to an undesired line shape. The system (14) can also detect the failure mode that occurs when the opaque layer (22) is broken through by detecting the plasma spectral component produced by the work piece material, along with the plasma produced by the opaque layer.
