Abstract: A method of evaluating and validating additive manufacturing operations includes generating a multidimensional space defined by a plurality of bounds, each of the bounds being defined on a distinct parameter of an additive manufacturing process and each of the bounds being directly related to the occurrence of a downskin roughness flaw, each of the parameters being a dimension in a multi-dimensional coordinate system, determining a coordinate position of at least one additive manufacturing operation within the multi-dimensional coordinate system, and categorizing the operation as free of downskin roughness flaws when the coordinate position is within the multi-dimensional space.

Abstract: A vibration resistant fan guide vane for a gas turbine engine is provided. The fan guide vane comprises a vibration damping component made of a MAXMET composite. The damping component may be a cover that covers some or all of the fan guide vane body. Alternatively, portions of the fan guide vane body or the entire vane body may be made from MAXMET composites. The disclosure makes use of the ultrahigh, fully reversible, non-linear elastic hysteresis behavior that MAXMET composites exhibit during cyclic elastic deformation in order to damp vibration.

Abstract: A method of removing scale from a casting may include positioning the casting relative to a laser emitter. The casting may comprise a superalloy and the scale may have formed on the surfaces thereof, with the scale being a byproduct of a method of manufacturing the casting. The method may also include passing a laser beam emitted from the laser emitter across the casting such that the laser beam causes the scale to at least one of crack, break, shatter, and spall. The superalloy may be a nickel-based superalloy and the scale may include a metal carbide layer.

Abstract: A process for coating a gas turbine blade with an abrasive. The process includes positioning the gas turbine blade in a nest, the gas turbine blade comprising a tip having a top surface; prepositioning a metal powder material on the top surface; fusing the metal powder material to the top surface by use of a laser to form a base layer on the top surface; prepositioning an abrasive composite material on the base layer opposite the top surface; fusing the abrasive composite material to the base layer by use of the laser to form an abrasive coating on the base layer; and removing the gas turbine blade from the nest.
