초록 ▼

A hybrid additive manufacturing method comprises building an additive structure on a pre-sintered preform base, wherein building the additive structure comprises iteratively fusing together a plurality of layers of additive material with at least a first layer of additive material joined to the pre-sintered preform base, and wherein the pre-sintered preform base comprises an initial shape. The hybrid additive manufacturing method further comprises modifying the initial shape of the pre-sintered preform base comprising the additive structure into a modified shape comprising the additive structure, and, joining the pre-sintered preform base in its modified shape to a component.

대표청구항 ▼

1. A hybrid additive manufacturing method of producing a hybrid turbine component comprising: building an additive structure, wherein the additive structure comprises a plurality of cooling walls on a pre sintered preform base, wherein the plurality of cooling walls are spaced apart from each other with channels therebetween and wherein building the plurality of cooling walls comprises iteratively fusing together a plurality of layers of additive material with at least a first layer of additive material joined to the pre-sintered preform base, and wherein the pre-sintered preform base comprises an initial flat and planar shape;modifying the initial shape of the pre-sintered preform base comprising the plurality of cooling, walls into a modified shape such that the plurality of cooling walls form a non-planar shape;joining the pre-sintered preform base in its modified shape to a turbine component to produce the hybrid turbine component wherein the pre-sintered preform base comprises a mixture comprising a base ahoy and a second alloy, the base alloy and the turbine component share a common composition. 2. The hybrid additive manufacturing method of claim 1, wherein the modified shape comprises a non-planar surface. 3. The hybrid additive manufacturing method of claim 2, wherein the non-planar surface comprises a curved surface. 4. The hybrid additive manufacturing method of claim 1, wherein joining the pre-sintered preform base in its modified shape to the turbine component comprises joining the pre-sintered preform base to a curved surface of the turbine component. 5. The hybrid additive manufacturing method of claim 1, wherein the turbine component comprises a nozzle, and wherein joining the pre-sintered preform base in its modified shape to the nozzle comprises joining the pre-sintered preform base to an interior surface of the nozzle. 6. The hybrid additive manufacturing method of claim 1, wherein iteratively fusing together the plurality of layers of additive material comprises using a powder bed additive manufacturing process. 7. The hybrid additive manufacturing method of claim 1, wherein the mixture comprising the base alloy comprising 30 weight percent to 90 weight percent of the mixture and the second alloy comprising a sufficient amount of melting point depressant have a lower melting temperature than the base alloy.
