摘要： A method for making a turbine airfoil (18) includes providing a mold core (40) and an outer shell (42) which cooperatively define a cavity in the shape of a hollow airfoil (18) having an outer wall, a root, and a tip. A tip portion of the core (40) extends completely through the portion of the cavity defining the tip of the airfoil (18). The core (40) is restrained to prevent movement between the core (40) and outer shell (42). Molten metal is introduced into the cavity and solidified to form an airfoil (18) having at least one outer wall which defines an open tip and a hollow interior. A metallic tip cap is formed on the outer wall which substantially closes off the open tip. The tip cap may be formed by packing the airfoil (18) with metallic powder; and laser sintering the exposed powder so as to form a tip cap which is metallurgically bonded to the outer wall.

摘要： A method is described, for treating a superalloy substrate (32) which includes at least one cavity (33) containing adherent metal oxide material on its surface (31). A short-pulsed, high repetition rate laser beam (46) is directed against the cavity surface for a period of time sufficient to remove substantially all of the adherent metal oxide material. The laser beam (46) is characterized by a peak power density in the range of about 10 megawatts/cm2 to about 10 gigawatts/cm2. In another embodiment, a high-power, short-pulsed, high repetition rate laser beam is directed to a region (62) on the substrate (64) which includes the cavity (60), under laser operational conditions which are capable of cutting into the superalloy material; so that a boundary region (66) is formed within the substrate, which encloses the cavity. The cavity can be a crack in a turbine blade, and the crack (60) can be repaired after treatment, by welding, or by another suitable technique.
