Abstract: Joining process, joined article, and process of fabricating a joined article are disclosed. The joining process includes providing a consumable electrode comprising a first material and a second material, melting the consumable electrode by a current-induced melting or remelting, and re-solidifying the first material and the second material to form a dissimilar ingot having a first region being a re-solidification of the first material and a second region being a re-solidification of the second material. The joined article includes the first region and the second region; the dissimilar ingot at least partially defines the joined article. The process of fabricating includes providing the dissimilar ingot, positioning the dissimilar ingot within a die, and applying force from the die to compress the dissimilar ingot, thereby forming the joined article.

Abstract: A method for hardfacing a metal article is disclosed including applying a first pass of a metal composition to a surface of the metal article along a first application path, applying a second pass of the metal composition to the surface along a second application path, and applying a third pass of the metal composition to the surface along a third application path between the first application path and the second application path. The first pass and the second pass form a hardfacing perimeter, and the third pass fills in the hardfacing perimeter.

Abstract: A method for closing a plurality of holes penetrating from a first surface of a metal article through a second surface of the metal article is disclosed including applying the metal composition to the first surface along a bridging application path. The bridging application path passes over the plurality of holes between a first edge of each of the plurality of holes and a second edge of each of the plurality of holes. Applying the metal composition along the bridging application path closes the plurality of holes.

Abstract: A method for closing a hole penetrating a hole height from a first surface of a metal article through a second surface of the metal article is disclosed including removing a portion of the metal article surrounding the hole from the metal article. The portion includes a depth extending from the first surface into the metal article and terminating prior to the second surface. Removing the portion forms a support surface within the hole adjacent and opposite to the second surface. A metal support structure is disposed within the hole on the support surface, and a metal composition is applied into the hole and onto the metal support structure. The metal support structure, the metal composition, and the metal article are fused together.

Abstract: A method for forming a turbine component is disclosed, including applying a metal composition to a structure by an additive manufacturing technique and lengthening the structure by the additive manufacturing technique. The structure is a transition piece or a combustion liner-transition piece assembly. Lengthening the structure forms a structure extension. A picture frame is formed on an outer surface of the structure extension by the additive manufacturing technique.

Abstract: In some embodiments, a method of welding includes welding at least one fill bead to fill at least one gap on a substrate with arc scanning by an arc welder. The gap is defined by at least one weld bead on the substrate. The weld beads are non-overlapping. A welded article includes a substrate including a crack-prone superalloy and at least one weld bead and at least one fill bead welded on the substrate. The fill bead, the weld bead, and a heat-affected zone of the substrate are micro-crack-free and macro-crack-free. In some embodiments, a method of welding includes welding weld beads on a substrate and welding fill beads on the substrate with an arc welder while arc scanning. The fill beads fill the gaps between neighboring pairs of weld beads. The fill beads are welded in a non-sequential order.

Abstract: A method for forming a vertically cracked thermal barrier coating is disclosed including positioning an article relative to a heat source. The article includes a thermal barrier coating disposed on a first surface of a substrate, and the substrate includes a second surface distal across the substrate from the first surface. Heat is applied locally to at least one discrete portion of the second surface of the substrate. At least one vertical crack in the thermal barrier coating is formed disposed over the at least one discrete portion. An article is disclosed including a substrate and a vertically-cracked thermal barrier coating disposed on the substrate. The vertically cracked thermal barrier coating includes at least one vertical crack in the thermal barrier coating and at least one of a low density of less than 85% of a theoretical density for the thermal barrier coating and a selective crack distribution.

Abstract: A method treats a brush seal at a tip end of the brush seal. The method includes contacting the tip end of the brush seal to an oxidation-resistant, wear-resistant coating composition and heat-treating a distal portion of the bristles to form an oxidation-resistant, wear-resistant coating on the distal portion from the oxidation-resistant, wear-resistant coating composition. A brush seal includes a brush support and bristles extending from the brush support with a distal portion coated by an aluminide diffusion coating. A brush seal assembly includes a non-rotary component and a rotary component. The non-rotary component includes a brush seal including a bristle pack. The bristle pack includes bristles extending from a brush support with a distal portion coated by an aluminide diffusion coating. The rotary component has a sealing surface contacting the distal portion of the brush seal to form a turbine seal between the rotary component and the non-rotary component.
