Abstract:
Thermally-conductive ceramic and ceramic composite components suitable for high temperature applications, systems having such components, and methods of manufacturing such components. The thermally-conductive components are formed by a displacive compensation of porosity (DCP) process and are suitable for use at operating temperatures above 600°C without a significant reduction in thermal and mechanical properties.
Abstract:
The present disclosure relates to a brazed superabrasive assemblies and method of producing brazed superabrasive assemblies. The brazed superabrasive assemblies may include a plurality of braze alloy layers that are positioned opposite a stress relieving layer. The stress relieving layer may have a solidus temperature that is greater than a solidus temperature of the plurality of braze alloy layers.
Abstract:
Embodiments of the invention generally relate to solid state battery structures, such as Li-ion batteries, methods of fabrication and tools for fabricating the batteries. One or more electrodes and the separator may each be cast using a green tape approach wherein a mixture of active material, conductive additive, polymer binder and/or solid electrolyte are molded or extruded in a roll to roll or segmented sheet/disk process to make green tape, green disks or green sheets, A method of fabricating a solid state battery may include: preparing and/or providing a green sheet of positive electrode material; preparing and/or providing a green sheet of separator material; laminating together the green sheet of positive electrode material and the green sheet of separator material to form a laminated green stack; and sintering the laminated green stack to form a sintered stack comprising a positive electrode and a separator.
Abstract:
A method for making a treated super-hard structure, the method including providing a super-hard structure comprising super-hard material selected from polycrystalline cubic boron nitride (PCBN) material or thermally stable polycrystalline diamond (PCD) material; subjecting the super-hard structure to heat treatment at a treatment temperature of greater than 700 degrees centigrade at a treatment pressure at which the super-hard material is not thermodynamically stable, for a treatment period of at least about 5 minutes to produce the treated super-hard structure.
Abstract:
A component comprising a silicon-based substrate and a braze-based protective coating disposed on the silicon-based substrate. The braze-based coating comprises a brazed layer, wherein the brazed layer comprises at least one intermetallic compound. A scale layer may be formed on the brazed layer. An environmental barrier coating may be disposed directly on the brazed layer or directly on the scale layer. A thermal barrier coating may be disposed on the environmental barrier coating. Methods for making a Si-based component having a braze-based protective coating are also disclosed.
Abstract:
An electrostatic chuck with a top surface adapted for Johnsen-Rahbek clamping in the temperature range of 500C to 750C. The top surface may be sapphire. The top surface can be attached to the lower portion of the electrostatic chuck using a braze layer able to withstand corrosive processing chemistries. A method of manufacturing an electrostatic chuck with a top surface adapted for Johnsen-Rahbek clamping in the temperature range of 500C to 750C is provided.
Abstract:
A method for joining engine components includes positioning a first plurality of thermal protection structures across a thermal protection space between a first thermal protection surface and a second thermal protection surface. The first and second engine components are locally joined by forming a first plurality of transient liquid phase (TLP) or partial transient liquid phase (PTLP) bonds along corresponding ones of the first plurality of thermal protection structures between the first thermal protection surface and the second thermal protection surface. The second thermal protection surface is formed from a second surface material different from a first surface material of the first thermal protection surface.
