    Abstract: A layer of a powdered material (4) is heated with an energy beam (10) such that at least one gas-generating agent (8) reacts to form at least one gaseous substance (14) to produce a void-containing coating (16) adhered to the surface of a substrate (2). The powdered material may contain a metallic material, a ceramic material, or both, and may also contain at least one of a flux material (32) containing the gas-generating agent and an exothermic agent (64). The heating may occur using a laser beam and may induce a melting or sintering of the powdered material to produce the void-containing coating. A gas turbine engine component exhibiting improved thermal and mechanical properties may be formed to include the void-containing coating, which may take the form of a bond coating, a thermal barrier coating, or both.

    Abstract: A continuous flow reactor for the efficient synthesis of nanoparticles with a high degree of crystallinity, uniform particle size, and homogenous stoichiometry throughout the crystal is described. Disclosed embodiments include a flow reactor with an energy source for rapid nucleation of the procurors following by a separate heating source for growing the nucleates. Segmented flow may be provided to facilitate mixing and uniform energy absorption of the precursors, and post production quality testing in communication with a control system allow automatic real-time adjustment of the production parameters. The nucleation energy source can be monomodal, multimodal, or multivariable frequency microwave energy and tuned to allow different precursors to nucleate at substantially the same time thereby resulting in a substantially homogenous nanoparticle. A shell application system may also be provided to allow one or more shell layers to be formed onto each nanoparticle.
