摘要： A method of forming an erosion shield (326) for a turbine blade (300) includes depositing a layer of filler material (402 or 328) defining an upper surface (416). The method also includes depositing a layer of erosion-resistant material (422 or 330) across the upper surface (416) of the layer of filler material (402 or 328). An interface (340) is defined between the layer of filler material (402 or 328) and the layer of erosion-resistant material (422) and has a shape of the upper surface (416). The method also includes machining the layer of filler material (402 or 328) to produce the erosion shield (326). The erosion shield (326) has the layer of erosion-resistant material (422 or 330), the machined layer of filler material (328), and the interface (340) defined therebetween. An inner surface (336) of the erosion shield is defined by the machined layer of filler material (328) that is sized and shaped for attaching to a leading edge (304) of the turbine blade (300). Each of the interface (340) and the inner surface (336) extend a length of the erosion shield (326).

摘要： A method of manufacturing an erosion-shielded turbine blade includes providing a turbine blade (300) for use with a rotary machine (110 and/or 210). The turbine blade (300) includes an airfoil (302) extending between a root (312) and a tip (316). The airfoil (302) includes a pressure side (308) and an opposite suction side (310), and each of the pressure and suction sides (308, 310) extends between a leading edge (304) and a trailing edge (306). The method also includes printing a green body part (402) by an additive manufacturing process by selectively depositing a binder solution (428) across a particulate erosion-resistant material (412), and sintering the green body part (402) to produce a post-sintering erosion shield (326) that includes densified erosion-resistant material. The method also includes coupling the erosion shield (326) to the leading edge (304) of the turbine blade (300).
