Abstract: A method of fabricating a component includes preparing at least a portion of a surface of the component and forming a pre-sintered preform hybrid hardface mixture comprising combining a predetermined portion of at least one hardfacing material with a predetermined portion of at least one brazing material. The method further includes forming a pre-sintered preform using additive manufacturing, the pre-sintered preform having a near-net shape and forming a sintered preform. The method further includes positioning the sintered preform on the component and fixedly coupling the sintered preform to at least a portion of the component via brazing.

Abstract: A method for counteracting tensile stress in an article is disclosed, including heating the article and applying compressive stress to the article along a compressive stress vector, the compressive stress vector including a compressive stress vector component opposite in direction to a tensile stress vector of a thermally-induced tensile stress of the article. The compressive stress is applied by thermally-induced autogenous pressure by a fixture contacting the article. A fixture for counteracting tensile stress is disclosed, including a first compression member and a second compression member, and a position lock connecting the first compression member to the second compression member and reversibly fixing the first compression member relative to the second compression member. The first compression member and the second compression member include compressive surfaces having mating conformations for surfaces of an article. The position lock includes a material composition.

Abstract: A process for treating a component comprising the steps of capturing a digital image of a gap in a portion of a component. The gap is characterized as having gap walls, a length and at any point along its length as having the features of an inner width between the gap walls, an outer width between the gap walls, and a depth. One or more of such features is measured at one or more points along all or a portion of the length of the gap. The measurements are used to determine a water jet cleaning path, a cleaning edge relative to a gap wall and path angle. A water jet is passed along all or a portion of the selected path to remove debris and/or a portion of a gap wall. The treated gap is then processed further to join the gap edges using a suitable sealing method.

Abstract: A hybrid article is disclosed including a coating disposed on and circumscribing the lateral surface of a core having a core material. The coating includes about 35% to about 95% of a first metallic material having a first melting point, and about 5% to about 65% of a second metallic material having a second melting point lower than the first melting point. A method for forming the hybrid article is disclosed including disposing the core in a die, forming a gap between the lateral surface and the die, introducing a slurry having the metallic materials into the gap, 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. Closing the aperture includes brazing the hybrid article to the article, welding the aperture with the hybrid article serving as weld filler, or a combination thereof.

Abstract: An article treatment method includes positioning an article having a base material. A weld filler material is applied to the base material by welding to form a treated article. The weld filler material includes at least one temperature depressant element at a concentration sufficient to form potential eutectic-containing zones in the welded article. The potential eutectic-containing zones contain the at least one temperature depressant element. The welded article is heated to a temperature sufficiently high and for a time sufficiently long to form at least partially liquefied eutectic-containing zones. The at least partially liquefied eutectic zones are capable of flow into cracks formed during the welding.
