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: Provided is a method for fabricating a component having a high temperature resistant surface. The method includes the steps of providing a metallic powder to a base material, heating the metallic powder to a temperature sufficient to join at least a portion of the metallic powder to form an initial layer, sequentially forming additional layers over the initial layer by heating a distributed layer of the metallic powder to a temperature sufficient to join at least a portion of the distributed layer of the metallic powder and join the formed additional layers to underlying layers, repeating the steps of sequentially forming the additional layers over a previously formed layer to form a formed portion of the component, and optionally removing the formed portion of the component and a portion of the base material. Also provided is a component having a high temperature resistant surface.
