Abstract: A method for treating a component and a treated component are provided. The method includes the steps of machining a tapered slot in the component. The tapered slot is measured to determine dimensions. An insert is formed to have a corresponding geometry to the tapered slot with a braze gap between an outer surface of the insert and an inner surface of the tapered slot. A layer of a braze material is deposited on the outer surface of the insert, where a thickness of the layer corresponds to the braze gap. The layer of the braze material on the outer surface of the insert is sintered to fabricate a diffusion layer. The insert is positioned into the tapered slot. The diffusion layer is brazed to join the insert to the taper slot. The treated component includes a surface having a tapered slot, an insert, and a braze joint.

The coating is sinter-bonded to the core. A method for forming the hybrid article is disclosed including disposing the core in a die, introducing a slurry having the metallic materials into a gap between the lateral surface and the die, and sintering the slurry, forming the coating. A method for closing an aperture of an article is disclosed including inserting the hybrid article into the aperture, and brazing the hybrid article to the article, welding the aperture with the hybrid article serving as weld filler, or both.

Abstract: A fabricated article includes a substrate and one or more turbulators formed on the substrate. Each of the one or more turbulators includes at least one root portion providing a concave transition between the substrate and the turbulator. In some embodiments, the fabricated article is formed by a turbulator fabrication process. The turbulator fabrication process includes concurrently directing the first fusion energy toward a first side of the turbulator material extending from the substrate and the second fusion energy toward a second side of the turbulator material opposite the first side and extending from the substrate. The directing of the first fusion energy and the second fusion energy shapes the first side of the turbulator material to have a first contour and the second side of the turbulator material to have a second contour, thereby forming the one or more turbulators on the substrate.
