摘要： A method (900) of making an article of manufacture is provided and includes the steps of (910) spraying a first coating onto a substrate, and (920) depositing a second coating on the first coating by 3-D printing a material disposed in a pattern. The pattern includes ridges (16) disposed at a base surface (20) of a turbine part. Each ridge (16) defined by first (30) and second (32) sidewalls, each sidewall (30,32) having a first (31) and second (33) end. The ends (30,33) extend from the base surface (20), the sidewalls (30,32) slope toward each other until meeting at second ends (33) of respective first (30) and second (32) sidewalls defining a centerline (22) and a top portion (34) of the ridge (16). The sidewalls (30,32) are inclined with substantially equal but opposite slopes with respect to the base surface (20). The ridges (16) correspond to a back portion (11) of a turbine bucket and are oriented at a first angle (48) with respect to an axis of rotation of the bucket.

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.
