摘要： A system for in situ inspection of a surface of a hot gas component of a turbine includes a robot having an elongated inspection arm extending toward the surface of the hot gas component; and an inspection head carried adjacent an end of the inspection arm remote from controls for the robot. The inspection head is manipulated by the inspection arm to locate the inspection head adjacent interior wall portions defining the hot gas component including by displacing the inspection head in a generally axial direction and generally radially toward a wall portion of the hot gas component being inspected. The inspection head is configured with a UV system to excite and detect fluorescence from a taggant material disposed in a coating on the hot gas component.

摘要： A sensor measures temperature in stationary components of electrical machines using fiber optics. An optical fiber is embedded in a non-metallic ribbon. Notches are cut in the ribbon to effect bends that accommodate a shape of a stationary component. The ribbon and optical fiber are attached to the stationary component. A series of laser pulses can be injected from at least one end of the optical fiber, and the stationary component temperature can be monitored by interrogation of reflections from the series of laser pulses.

摘要： A method facilitates inspection of a component surface. The method comprises positioning a surface of the component to be inspected in an optical path of at least one infrared radiation detector, heating the component surface using electromagnetic radiation to cause an increase in radiance from a defect present at the component surface, and detecting temperature variations within the component surface using the at least one infrared radiation detector, such that the surface irradiance is measured at predetermined locations across the component surface. The method further comprises detecting cracks in the component by analyzing radiation transient response data received by the infrared radiation detector, and correlating the temperature variations to the radiation transient response data to determine a depth of the detected cracks.

The electrically non-conducting material has a thermal expansion coefficient such that each of the films remains adhered to adjacent films through at least one cycle of extreme operating temperature. In addition, communication links can be provided to transmit the measurement representing the condition of the turbine engine to a remote user.

摘要： An infrared inspection system and an induction heating system used in conjunction enable the inspection of rubber coated rolls, such as rolls used in the pulp and paper industry. The system effects non-destructive inspections of rubber coated rolls to detect a debonded condition between the metal core and rubber coating. The method includes supporting a roll for inspection, evenly heating or cooling the roll, and observing a thermal transient of the roll generated by the evenly heating process. Using an infrared camera, observed areas that are not transferring heat uniformly with respect to neighboring areas are suspected debonded areas.

摘要： A method for determining past-service conditions and/or remaining useful life of a component of a combustion engine and/or a thermal barrier coating (“TBC”) of the component comprises providing a photoluminescent (“PL”) material in the TBC, directing an exciting radiation at the TBC, measuring the intensity of a characteristic peak in the emission spectrum of the PL material, and correlating the intensity of the characteristic peak or another quantity derived therefrom to an amount of a new phase that has been formed as a result of the exposure of the component to extreme temperatures. An apparatus for carrying out the method comprises a radiation source that provides the exciting radiation to the TBC, a radiation detector for detecting radiation emitted by the PL material, and means for relating a characteristic of the emission spectrum of the PL material to the amount of the new phase in the TBC, thereby inferring the past-service conditions or the remaining useful life of the component.

摘要： A method of objectively evaluating a surface mark provides an objective test methodology for the optical quantification of surface marks. The method may include the steps of reproducibly producing a surface mark on an object and optically evaluating the surface mark. The surface mark may be reproducibly produced by loading a stylus, contacting a surface on the object with the loaded stylus and moving the object and the surface thereon relative to the loaded stylus so as to thereby produce a mark on the surface. Any surface mark is optically evaluated by optically producing images of the surface mark, electronically capturing the optically produced images and measuring selected parameters of the captured optically produced images.
