Abstract: Inventive techniques for forming unique compositions of matter are disclosed, as well as various advantageous physical characteristics, and associated properties of the resultant materials. In particular, particles comprising polymer matrices are characterized by having carbon disposed within the polymer matrix structure thereof. The carbon is primarily, or entirely, present at interstitial sites of the polymer matrix, and may be present in amounts ranging from about 15 wt % to about 90 wt %. The carbon, moreover, forms covalent bonds with both atoms of the polymer matrix and other carbon atoms present in, but not part of, the matrix. This facilitates substantially homogeneous dispersal of the carbon throughout the resultant material, conveying unique and advantageous properties such as strength-to-weight ratio, density, mechanical toughness, sheer strength, flex strength, hardness, anti-corrosiveness, electrical and/or thermal conductivity, etc. as described herein. In some approaches, the resultant materials may be powderized or pelletized.

Abstract: Apparatuses and methods for producing covetic materials by exciting a hydrocarbon gas with pulse microwaves to form hydrocarbon radicals in a hot first region of a microwave reactor. Graphene nanoplatelets are formed by the nucleation, growth and assembly of the hydrocarbon radicals, and contact a metal melt introduced downstream of the hot region to produce a mixture of molten metal and graphene nanoplatelets which assemble in-flight to form covetic materials. Graphene planes are infused in the metal matrix to achieve carbon loadings of at least 60%.

Abstract: A method of manufacturing a feedthrough dielectric body for an active implantable medical device includes the steps of forming a ceramic body in a green state, or, stacking discrete layers of ceramic in a green state upon one another and laminating together. The ceramic body has a first side opposite a second side. At least one via hole is formed straight through the ceramic body extending between the first and second sides. At least one via hole is filled with a conductive paste. The ceramic body and the conductive paste are then dried. The ceramic body and the conductive paste are isostatically pressed at above 1000 psi to remove voids and to form a closer interface for sintering. The ceramic body and the conductive paste are sintered together to form the feedthrough dielectric body. The feedthrough dielectric body is hermetically sealed to a ferrule.

Abstract: Methods for producing multilayer heat sinks utilizing low temperature sintering processes are provided. In one embodiment, the method includes forming a metal particle-containing precursor layer over a first principal surface of a first metal layer. The first metal layer and the metal particle-containing layer are then arranged in a stacked relationship with a second metal layer such that the precursor layer is disposed between the first and second metal layers. A low temperature sintering process is then carried-out at a maximum process temperature less than a melt point of the metal particles to transform the precursor layer into a sintered bond layer joining the first and second metal layers in a sintered multilayer heat sink. In embodiments wherein the sintered multilayer heat sink is contained within a heat sink panel, singulation may be carried-out to separate the sintered multilayer heat sink from the other heat sinks within the panel.

Abstract: Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, a printer is configured to further fabricate an interface layer between the object and the support structure in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering.

Abstract: A process for applying a low coefficient of friction coating to interacting parts of a mechanical device. The low coefficient coating is comprised of nanoparticles of a metal melting below about 400° C., preferably bismuth. Interacting parts of a mechanical device, prior to assembly of the mechanical device, are submerged in a dispersion of the nanoparticles, then heated to an effective temperature, then cooled, thereby resulting in a coating of the nanoparticles onto the interacting parts.

Abstract: A metal matrix self-lubricating composite and a manufacturing method therefor. The metal matrix self-lubricating composite comprises a metal matrix and a mixture layer compounded on a surface of the metal matrix, the mixed layer comprising a copper alloy and a self-lubricating material. The method for manufacturing the metal matrix self-lubricating composite comprises the following steps: a) sintering copper alloy powder on a surface of a metal matrix to form a copper alloy layer on the surface of the metal matrix; b) blade-coating or dip-coating a lubricating material on a surface of the copper alloy layer, and performing vacuumization to obtain a metal plate, and drying the metal plate; c) repeating step b) for multiple times; and d) sintering the metal plate obtained in step c) to obtain the metal matrix self-lubricating composite. In the present invention, a vacuumization mode is used and vacuumization operations are repeated, so that a dense mixture layer on which a self-lubricating material is dispersed on a copper alloy is formed, and the metal matrix self-lubricating composite has good lubricity and abrasion resistance.
