摘要:
Different kinds of printing pastes or inks are utilized in various combinations to develop multiple ceramic dielectric layers on graphitic substrates in order to create effective dielectric ceramic layers that combine good adhesion to both graphitic substrates and printed copper traces, and strong insulating capability. The pastes or inks may comprise a high thermal conductivity powder.
摘要:
The invention relates to a method for coating, by means of a chemical vapour deposition (CVD) technique, a part with a coating (PAO) for protecting against oxidation. The method enables the preparation of a refractory coating for protecting against oxidation, having a three-dimensional microstructure, which ensures the protection against oxidation at a high temperature, generally at a temperature above 1200° C., for materials that are sensitive to oxidation, such as composite materials, and in particular carbon/carbon composite materials.

The present invention provides a process for producing a metalized substrate in which a predetermined metal paste composition is applied onto a sintered nitride ceramic substrate (10); the resultant is fired in a heat-resistant container at a predetermined condition; and the substrate (10) and a metal layer (30) are bonded together to each other through a titanium nitride layer (20).
摘要:
A method for manufacturing a metal-ceramic substrate with at least one metallization, patterned by etching, on at least one surface side of a laminar ceramic material. The metal-ceramic substrate includes a base substrate made of an aluminum-nitride or silicon-nitride ceramic. The metallization is applied by active soldering before patterning. An intermediate layer made of an oxidic ceramic is provided between the at least one metallization and the base substrate.
摘要:
Densified composites of a metal such as copper or aluminum with a titanium-silicon-carbide or titanium-aluminum-carbide ceramic material are prepared by forming the ceramic material into a body, and infiltrating the body with the molten metal. The metal is able to rapidly penetrate into void spaces, between grain boundaries and even into the crystal structure of the ceramic grains to form a composite. The starting ceramic material may be previously densified, in which case various types of gradient structures can be produced easily. The process can be operated at low pressures, and so the hot pressing methods that normally must be used to densify these ceramic materials can be avoided.

摘要:
A method for manufacturing metallized aluminum nitride substrate. The method includes: Step A for forming a high-melting point metal layer over a sintered aluminum nitride substrate; Step B for forming over the high-melting point metal layer an intermediate metal layer of at least one selected from the group of: nickel, copper, copper-silver, copper-tin, and gold by plate processing; and Step C for forming a surface metal layer containing silver as a main component over the intermediate metal layer by coating a silver paste whose glass component content is 1 mass % or less and firing under nonoxidizing atmosphere. By this method, it is capable of forming a glass component-free silver layer which is adhered at a high degree of adhesion strength onto the high-melting point metal layer formed over the aluminum nitride substrate as a top face by thick-film method using a silver paste which makes thick-membrane forming easier.
