摘要： The present invention is directed to a method for changing the color of colored natural diamonds. The method includes placing a discolored natural diamond in a pressure-transmitting medium which is consolidated into a pill. Next, the pill is placed into a high pressure/high temperature (HP/HT) press at elevated pressure and elevated temperature for a time sufficient to improve the color of the diamond. The diamond may be exposed at elevated-pressure and elevated-temperature conditions within the graphite-stable region of the carbon-phase diagramnullwithout significant graphitization of the diamond, or above the diamond-graphite equilibrium and within the diamond-stable region of the carbon-phase diagram. Finally, the diamond is recovered from said press. Colorless Type Ia and Type II diamonds may be made by this method.

摘要： A cell for forming a composite hard material and hard materials and methods of forming composite hard materials. A cell (10) in which the article is formed includes a talc outer sleeve (12), a glass sleeve (14) and a reflecting foil (22). A heater (18) is arranged inwardly of the foil (22) and a barrier layer (16) is arranged inwardly of the glass sleeve (14). A central column (20) is defined for receiving the charge of material (50) from which the hard composite material is to be formed. The charge material is located in a mold (76, 100) which can define the final shape of the article thereby avoiding the need for additional machining, and the mold and charge material are subject to high temperature and pressure to form the composite material while maintaining the charge subject to hydrostatic pressure during the application of pressure and high temperature and maintaining a low temperature gradient across the charge during formation of the composite hard material to reduce uneven pressurization of the composite hard material. The article may also be formed by forming first and second mixtures (120, 130) of composite hard material so as to form an outer surface on the article which has a higher hard particle content than an interior core portion of the article.

摘要： A method and apparatus for fabricating and drying wafers, including micro-electro-mechanical system (MEMS) structures, in a second, supercritical processing fluid environment. The apparatus utilizes an inverted pressure vessel connected to a supercritical processing fluid supply and recover system, with an internal heat exchanger connected to external heating and cooling sources, which is closed with a vertically movable base plate. A wafer cassette configured for supporting multiple wafers is submerged in a first processing fluid within a container, which is installed on the base plate for insertion into the pressure vessel. Vessel inlet and outlet tubes extend vertically downward from the ceiling of the pressure vessel to nearly the base plate. Container inlet and outlet tubes extend vertically downward from the ceiling of the pressure vessel to inside the container and nearly to the bottom of the container. The tubes provide for displacement of the first processing fluid with the second processing fluid still in a liquid state, from which it is raised to supercritical state.

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： A method for forging, or hot working bulk ceramics, including high temperature superconductors and other sensitive materials, under precisely controlled conditions of pressure, temperature, atmospheric composition, and strain rate. A capsule with massive end plates and with an independent gas supply is located in a modified hot isostatic press (HIP), designed to operate at pressures of up to 200 MPa and at temperatures of up to 1000 C. Essentially uniaxial deformation of a pre-compacted disc with forces of up to 500,000 Newtons (50 tons), and over time scales from seconds to hours can be achieved by separately controlling the pressure in the capsule from that of its surroundings. The separate gas supply to the capsule can also maintain a specified gaseous atmosphere around the disc, up to the operating pressure of the equipment. The apparatus can be designed to tolerate oxygen concentrations of up to 20%.

摘要： The present invention describes a process for the compaction and densification of materials using heat and high pressure in which pressure is applied isostatically to the workpiece to be compacted, heat is applied to the pressurized workpiece as rapidly as feasible, effecting thereby full compaction and densification. Heating is terminated and the workpiece cooled while the workpiece is still pressurized. This process effects hot-isostatic-processing of workpieces while reducing the time such workpieces spend at elevated temperatures. The resulting parts can have novel structures, properties or compositions not obtained with other processing procedures.
