Abstract: A new class of multi-component rare earth multi-silicate materials has been created for use in harsh environments such as gas turbine engines. Moreover, by combining two-or-more rare earth disilicates the properties (for example, thermal expansion, thermal conductivity, etc.) can be tailored to fit specific applications, such as having a matching thermal expansion with that of silicon-based composites and a low thermal conductivity close to that of 1 W/m K. Applications can be extended for use with other material classes such as MCrAlY, MAX-phase, and refractory metal alloys, utilizing a thermal expansion of up to about 15?10?6 /° C. By mixing of specific sets of rare earth disilicates it is possible to obtain a high entropy or entropy stabilized mixture, and utilize features such as “sluggish diffusion”, and more.

The coating is comprised of a metal or metal alloy that is similar in composition to the substrate to be coated, further combined with a corrosion inhibiting material. The corrosion inhibiting material may be a refractory metal or metalloid. The method and apparatus for producing the coating allows for the corrosion inhibiting coating to have a supersaturated concentration of the corrosion inhibiting material alloyed with another metal or metal alloy. The method and apparatus allow for the selective vaporization of material sources to make the coating vapor, which are then entrained in a high speed gas flow that directs the coating vapor onto the substrate. Optional plasma assistance and application of a voltage to the substrate may be used. The coating may be customized for a variety of applications.

Abstract: A directed vapor deposition (DVD) method and system for applying at least one bond coating on at least one substrate for thermal barrier coating systems. To overcome the limitations incurred by conventional methods, the DVD system uses an electron beam directed vapor deposition (DVD) technique to evaporate and deposit compositionally and morphologically controlled bond coats at high rate. The present DVD system uses the combination of an electron beam and a combined inert gas/reactive gas carrier jet of controlled composition to create engineering films. In this system, the vaporized material can be entrained in the carrier gas jet and deposited onto the substrate at a high rate and with high materials utilization efficiency. The velocity and flux of the gas atoms entering the chamber, the nozzle parameters, and the operating chamber pressure can all be significantly varied, facilitating wide processing condition variation and allowing for improved control over the properties of the deposited layer.

Abstract: Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

Abstract: A method for producing three-dimensional space frames or truss structures from simpler components and space frames or truss structures produced by the associated method. The various components, which may be made from virtually any material, are shaped in such a way so that they may be fitted together to create a space frame or truss structure. The components may be held together by any available attachment means, or by the interaction of the components themselves. The method and associated components allows for the assembly of three-dimensional space frames or truss structures from planar materials, significantly reducing cost and manufacturing time. These space frames or trusses can then be used as structural members, as the interior load-bearing portions of sandwich panels, or in any situation where high-strength and light weight are desirable.

Abstract: A plasma generation process that is more optimized for vapor deposition processes in general, and particularly for directed vapor deposition processing. The features of such an approach enables a robust and reliable coaxial plasma capability in which the plasma jet is coaxial with the vapor plume, rather than the orthogonal configuration creating the previous disadvantages. In this way, the previous deformation of the vapor gas jet by the work gas stream of the hollow cathode pipe can be avoided and the carrier gas consumption needed for shaping the vapor plume can be significantly decreased.

Abstract: Methods and apparatuses for passive jet blast deflection or the like. Use of the passive jet blast deflector permits the efficient dispersal of a fast moving local heat source into the environment through passive means while providing a high strength structure. The jet blast deflector system may include a first plate, a second plate, and a cellular core disposed between them adapted to allow cooling ambient air to flow through the cellular core, wherein the first plate, second plate, and core are all seamlessly coupled heat pipes that form a single vapor core to facilitate the spreading and even storing of thermal energy. An ejector plate may be attached to the top of the second plate to create a low pressure zone as the heat source passes over it, thereby pulling the ambient air through the cellular core, facilitating the removal the thermal energy from the system.

Abstract: Methods and systems to manufacture lattice-based sandwich structures from monolithic material. Such methods and systems eliminate the bonding process which is conventionally used to join lattice based truss cores to facesheets to form sandwich structures. This bonded interface is a key mode of failure for sandwich structures which are subjected to shear or bending loads because the nodes transfer forces from the face sheets to the core members while the topology for a given core relative density dictates the load carrying capacity (assuming adequate node-bond strength exists). An aspect comprises a core and related structures that provide very low density, good crush resistance and high in-plane shear resistance. An aspect of the truss structures may include sandwich panel cores and lattice truss topology that may be designed to efficiently support panel bending loads while maintaining an open topology that facilitates multifunctional applications.
