The method of claim 2 wherein the alloy power has a composition substantially the same as an alloy composition of the airfoil.Ĥ. The method of claim 1 wherein step (e) is carried out by: (a) melting an alloy power using laser energy (b) introducing the melted powder into the at least one core support opening and (c) allowing the melted powder to cool and solidify in the at least one core support opening.ģ. A method for making a turbine airfoil, comprising: (a) providing a mold having: (i) a core (ii) an outer shell surrounding the core such that the core and the outer shell cooperatively define a cavity in the shape of an airfoil having at least one outer wall and (iii) a core support extending from the core to the outer shell through a portion of the cavity that defines the at least one sidewall (b) introducing molten metal alloy into the cavity and surrounding the core support (c) solidifying the alloy to form an airfoil casting having at least one outer wall which has at least one core support opening passing therethrough (d) removing the mold so as to expose the airfoil and (e) sealing the at least one core support opening in the airfoil with a metal alloy metallurgically bonded to the at least one outer wall.Ģ.
