Abstract: A method of forming a hybrid component having an axis of rotation includes forming a first substrate having a first interface surface and a first average grain size, forming a second substrate having a second interface surface and a second average grain size different from the first average grain size, and inertia welding the first and second substrates at a junction of the first and second interface surfaces to form a solid-state joint between the first and second substrates.

Abstract: A method of reworking or repairing a component includes removing a casting defect from a component manufactured of a non-fusion weldable base alloy to form a cavity that results in a through hole; sealing the through hole with a backing; and at least partially filling the cavity with a multiple of layers of a multiple of laser powder deposition spots, each of the multiple of laser powder deposition spots formed of a filler alloy, a first layer of the multiple of layers includes a perimeter of the multiple of laser powder deposition spots that overlap a wall of the cavity and the backing.

Abstract: A method for coating a part according to an aspect of the disclosure includes the step binding a metallic powder to a section of the part. The metallic powder is then energized which at least partially melts and resolidifies the metallic powder to form a first metallic coating. After the first layer of metallic coating is formed a second layer of metallic coating is deposited on substantially all of the part.
