Abstract: A method for smoothing surface roughness within an internal passageway is disclosed. In various embodiments, the method comprises developing a first sphere progression through a length of the internal passageway, each sphere within the first sphere progression having a first sphere diameter greater than or equal to a diameter of the internal passageway; and developing a second sphere progression through the length of the internal passageway, each sphere within the second sphere progression having a second sphere diameter greater than the first sphere diameter, whereby the inner surface of the internal passageway is smoothed, first by the first sphere progression and then by the second sphere progression.

Abstract: A method for smoothing surface roughness within a passageway is disclosed. In various embodiments, the method comprises flowing an abrasive media through the passageway and positioning a mandrel within the passageway, the mandrel being sized to create a gap between an outer surface of the mandrel and an inner surface of the passageway, wherein the abrasive media is caused to flow through the gap, abrading the inner surface of the passageway.

Abstract: An airfoil is disclosed. The airfoil may comprise a leading edge, a body portion and a trailing edge formed from a high-modulus plating. The body portion of the airfoil may be formed from a material having a lower elastic modulus than the high-modulus plating. The high-modulus plating may improve the stiffness of the trailing edge, allowing for thinner trailing edges with improved fatigue life to be formed.

Abstract: An exemplary mold assembly includes a mold providing a cavity, and a heating element configured to heat a first portion of the mold at a first rate to melt a first amount of metal powder within the cavity, and further configured to heat a second portion of the mold at a different second rate to melt a second amount of powder within the cavity. The heating element includes a portion on a first side of the cavity and a portion on an opposing, second side of the cavity. The heating element is configured to receive the mold such that the heating element extends circumferentially about an entire perimeter of the mold.
