摘要:A method for joining a ceramic or metal ceramic electrical heating element (1) to an electrical terminal (2) is disclosed, the heating element having been manufactured using micropyretic synthesis, the method for joining comprising the steps of preparing the electrical terminal by blending a combustible mixture and fashioning the mixture into a desired wet and uncombusted shape for the terminal, attaching the terminal to the element, drying the terminal portion of the terminal-element attachment and combusting the terminal portion of said terminal-element attachment by ignition at a temperature between about 150 °C and 1800 °C. An electrical terminal is disclosed, the terminal having been formed by micropyretic synthesis of a specific combustible composition. A heating element assembly for a heater is disclosed comprising a first and a second ceramic or metal ceramic electrical terminals, a plurality of ceramic or metal ceramic heating elements and a plurality of ceramic or metal ceramic coolers (3) which are used to connect said plurality of heating elements to each other.

摘要:A method of bonding a particle material to near theoretical density, includes placing a particle material in a die. In the first stage, a pulsed current of about 1 to 20,000 amps., is applied to the particle material for a predetermined time period, and substantially simultaneously therewith, a shear force of about 5-50 MPa is applied. In the second stage, an axial pressure of about less than 1 to 2,000 MPa is applied to the particle material for a predetermined time period, and substantially simultaneously therewith, a steady current of about 1 to 20,000 amps. is applied. The method can be used to bond metallic, ceramic, intermetallic and composite materials to near-net shape, directly from precursors or elemental particle material without the need for synthesizing the material. The method may also be applied to perform combustion synthesis of a reactive material, followed by consolidation or joining to near-net shaped articles or parts. The method may further be applied to repair a damaged or worn substrate or part, coat a particle onto a substrate, and grow single crystals of a particle material.

摘要:Provided are methods to convert—through a bottom-up approach—binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into lepidocrocitic nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can comprise nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances.

摘要:Apparatus and method for synthesizing nanostructures in a controlled process. An embodiment of the apparatus comprises a stage or substrate holder that is heated, e.g., resistively, and is the primary source of heating for the substrate for nanostructure synthesis. The substrate and substrate heater are enclosed in a chamber, e.g., a metal chamber, which is ordinarily at a lower temperature than are the substrate and substrate heater during synthesis. Some embodiments of the invention are particularly useful for chemical vapor deposition (CVD), low pressure CVD (LPCVD), metal organic CVD (MOCVD), and general vapor deposition techniques. Some embodiments of the present invention allow for in situ characterization and treatment of the substrate and nanostructures.

摘要:A hybrid beam deposition (HBD) system and methods according to the present invention utilizes a unique combination of pulsed laser deposition (PLD) technique and equipment with equipment and techniques that provide a radical oxygen rf-plasma stream to effectively increase the flux density of available reactive oxygen at a deposition substrate for the effective synthesis of metal oxide thin films. The HBD system and methods of the present invention further integrate molecular beam epitaxy (MBE) and/or chemical vapor deposition (CVD) techniques and equipment in combination with the PLD equipment and technique and the radical oxygen rf-plasma stream to provide elemental source materials for the synthesis of undoped and/or doped metal oxide thin films as well as the synthesis of undoped and/or doped metal-based oxide alloy thin films.
