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.

Abstract: At least one turbine component for a gas turbine includes a base component formed by casting and an article. The base component includes a platform. The article on the upper surface of the platform is formed by additive manufacturing. The article has a proximal face sized and shaped to cover at least a portion of the upper surface of the platform of the turbine component and a contoured distal face opposite the proximal face. The contoured distal face has a contour surface serving as at least a portion of a hot gas path surface of the turbine component. The contour surface is arranged and disposed to provide a controlled flow pattern of a working fluid across the contour surface based on a clock mounting location of the turbine component in a turbine.
