    摘要: A method for additive manufacturing with multiple materials. First (48), second (50), and third (52) adjacent powder layers are delivered onto a working surface (54A) in respective first (73), second (74), and third (75) area shapes of adjacent final materials (30, 44, 45) in a given section plane of a component (20). The first powder may be a structural metal delivered in the sectional shape of an airfoil substrate (30). The second powder may be a bond coat material delivered in a sectional shape of a bond coat (45) on the substrate. The third powder may be a thermal barrier ceramic delivered in a section shape of the thermal barrier coating (44). A particular laser intensity (69A, 69B) is applied to each layer to melt or to sinter the layer. Integrated interfaces (57, 77, 80) may be formed between adjacent layers by gradient material overlap and/or interleaving projections.

    摘要: A laser microcladding process utilizing powdered flux material (93b). A jet (92) of propellant gas containing powdered alloy material (93a) and the powdered flux material are directed toward a substrate (94). The powdered materials are melted by a laser beam (96) to form a weld pool (98) which separates into a layer of slag (100) covering a layer of clad alloy material (102). The flux material deoxidizes the weld pool and protects the layer of clad alloy material as it cools, thereby allowing the propellant gas to be nitrogen or air rather than an inert gas. In one embodiment, the substrate and alloy materials are superalloys with compositions beyond the traditional zone of weldability.

    摘要: The invention relates to a heat treatment method for monocrystalline or directionally solidified structural components. Said method comprises a heat treatment which results in dissolving at least one crystalline phase of the material of the structural component, referred to in the following as component material. The inventive method is characterized by carrying out the heat treatment by heating the structural component to a dissolution temperature required for dissolving the crystalline phase only in at least one first component area in which the stresses within the component material do not exceed a predetermined value. In at least one second component area in which the stresses within the component material exceed the predetermined value the material is only heated to a temperature below the dissolution temperature.
