Abstract
A method for manufacturing an engine component includes forming the component by deposition of powder, which is melted by a heat source, in subsequent Layers to form the component into a desired shape, the component having an outer surface, and re-melting at least part of the outer surface.
Claims18
A method for manufacturing an engine component comprising the steps of:
- forming the component on a substrate by adding molten metal in a layer by layer fashion to form the component into a desired shape, the component having an outer surface;
- and
- re-melting at least part of the outer surface such that material is relocated from one location to another desired location
- wherein the component formed on the substrate by adding molten metal in the layer by layer fashion comprises a plurality of layers, each of the plurality of layers having an edge surface including at least a portion having a convex shape, and wherein the re-melting is achieved through controlling a degree of re-melting by a heat source, thereby transforming the convex shape of the portion on a plurality of the plurality of layers into the desired shape having a single common at least partially concave curvature.
