23 Direct metal bonding on carbon-covered ceramic contact projections of a ceramic carrier US15088088 2016-03-31 US10000423B1 2018-06-19 Thomas Spann
Top and bottom metal plates of a DMB panel stack are simultaneously direct-bonded to the central ceramic sheet in a single high-temperature step. During this step, the DMB panel rests on an array of very small upwardly projecting ceramic contacts of a ceramic carrier. An amount of unoxidized carbon (e.g., a layer of graphite) is disposed on each contact projection such that an amount of carbon is disposed between the top of the contact projection and the metal oxide skin of the bottom metal plate. The carbon bonds with oxygen from the metal oxide skin, thereby preventing connection or direct-bonding of the ceramic contact projection to the second metal plate. This reduces imperfections in the metal of the bottom plate and reduces the amount of ceramic particles bonded to metal at contact sites. As a result, less post-bonding processing is required to make a high quality DMB substrate.

A method of joining metal and metal, or metal and ceramic parts, wherein a first metal part is selected and then processed to form a bond coat that will effectively bond to a sealing material which in turn bonds to a second metal or ceramic part without degrading under the operating conditions of electrochemical devices. Preferred first metal parts include alumina forming alloys from the group consisting of ferritic stainless steels (such as Fecralloys), austinetic stainless steels, and superalloys, and chromia forming alloys formed of ferritic stainless steels. In the case of chromia forming ferritic stainless steels, this bond coat consists of a thin layer of alumina formed on the surface, with a diffusion layer between the first metal part and this thin layer. The bond coat provides a good bonding surface for a sealing layer of glass, braze or combinations thereof, while at the same time the diffusion layer provides a durable bond between the thin alumina layer and the first metal part. In the case of alumina forming alloys, the bond coat consists of cauliflower-like growths of an aluminum oxide nodules embedded in the surface of the alumina forming alloys.

37 Eutectic bonding of metal to ceramic US699534 1991-05-14 US5108026A 1992-04-28 Ming-Yih Su; John W. Somers
An improved eutectic oxide bonding method is applied for bonding a metallic copper foil to a nonmetallic substrate by forming a liquid phase derived from a eutectic oxide composition. A metallic copper thin film is initially deposited onto the substrate and heated in a low oxygen atmosphere under suitable conditions to form a cuprous oxide film. A metallic copper foil is positioned on the substrate in contact with the cuprous oxide film. Preferably, the assembly is initially heated at a temperature below the eutectic melting point to soften the foil and promote intimate contact between the foil and the cuprous oxide film. Thereafter, the assembly is heated above the eutectic melting point to form a liquid phase at the interface of the foil and the cuprous oxide film, and maintained at the temperature for a time sufficient to dissolve the oxide film, whereupon the liquid phase wets the substrate. The assembly is cooled, and the liquid phase is solidified to bond the foil to the substrate. In addition to copper, the method may be adopted to bond foils of other metals, including chromium, iron, cobalt and nickel, using low melting eutectic oxides thereof.
