欠陥を直し微細構造を改変させるための付加製造された部品の再形成
Document Type and Number:
Japanese Patent JP6483088
Kind Code:
B2
Abstract:
A method to manufacture a component (10) comprising a columnar grain microstructure, the method comprising additively manufacturing a component (10),wherein the additively manufactured component comprises a polycrystalline microstructure; encasing the additively manufactured component (10) in a shell mold (22); wherein encasing the additively manufactured component (10) in the shell mold (22) comprises a process of: (a) dipping the entirety of the component (10) in a ceramic slurry to form a layer of the shell mold (22) on the entirety of the component (10), such that the layer is a ceramic layer; and (b) drying the layer of the shell mold (22); and (c) repeating steps (a) and (b) to increase a thickness of the shell mold (22); curing the shell mold (22); placing the encased additively manufactured component (10) in a furnace and melting the additively manufactured component (10) to form a melted component; solidifying the melted component (10) in the shell mold (22) to form a solidified component; and removing the shell mold (22) from the solidified component (10), wherein the solidified component comprises the columnar grain microstructure.
