  • Publication number: 20230366673
    Abstract: A method can comprise: scanning, via an optical scanner, a tip of an airfoil of a bladed rotor, the tip including a coating disposed thereon, the coating comprising a metal plating and a plurality of protrusions, each protrusion in the plurality of protrusions extending from the metal plating; comparing a coating parameter of the coating to a coating parameter threshold based on scanner data from the optical scanner; and determining whether the coating maintains sufficient coverage of the tip of the airfoil based on the comparing.

  • Patent number: 11181491
    Abstract: Aspects of the disclosure are directed to an analysis of a material of a component. A radiation source is activated to transmit radiation to the component. A beam pattern is obtained based on the component interfering with the radiation. The beam pattern is compared to a reference beam pattern. An anomaly is detected to exist in the material when the comparison indicates a deviation between the beam pattern and the reference beam pattern.

  • Patent number: 10458929
    Abstract: A system for the x-ray topography analysis of a sample, comprising in combination, a goniometer having a base, a tube arm rotatably associated with the base, a detector arm rotatably associated with the base, and a sample stage operatively associated with the base. The system also includes an x-ray source operatively coupled with the tube arm and is capable of emitting a non-collimated beam of x-rays. A collimator is operatively associated with the x-ray source and converts the non-collimated beam of x-rays into a collimated beam of x-rays having a quasi-rectangular shape with a divergence less than three degrees in all directions. A detector operatively coupled to the detector arm.

  • Patent number: 10370984
    Abstract: An airfoil includes an airfoil body that extends at least between leading and trailing edges, first and second sides, and radially inner and outer ends. The airfoil body includes an aluminum alloy that has a controlled crystallographic texture with respect to a predefined three-dimensional coordinate system.

  • Publication number: 20150253262
    Abstract: An x-ray diffraction system includes an x-ray source having a first interchangeable x-ray generating component, a second interchangeable x-ray generating component, an actuator and a controller operatively connected to the actuator. The first and second interchangeable x-ray generating components are interchangeable with one another. The actuator is operatively connected to the first and second interchangeable x-ray generating components. A method for non-destructive x-ray diffraction includes emitting a first x-ray beam from an x-ray source with a first x-ray generating component based on a first desired depth to measure a crystallographic signature of a sample at the first desired depth, interchanging the first x-ray generating component with a second x-ray generating component to form a modified x-ray source, and emitting a second x-ray beam from the modified x-ray source based on a second desired depth, to non-destructively measure a crystallographic signature of the sample at the second desired depth.
