  • Pulsed laser heating simulation of thermal damage on coated surface
    Patent number: 6568846
    Abstract: An apparatus and method for evaluating thermal barrier coating material on a surface of a part or component that is subjected to transient heat/thermal cycles. A pulsed laser heating apparatus that preferably uses lenses and optical fiber focusing components simulates conditions of brief heating on the test specimen. In the method of the invention, the temporal shape, spatial distribution, and total energy of the laser pulse are designed to produce a spot of uniform illumination and heat absorption on the test specimen that closely approximates the thermal loading that the specimen is expected to receive during use. The test specimen is then examined for thermally induced changes.
