Graphite and Carbon Bonded to Metals

Graphite bonding and carbon bonding is another aspect of ceramic to metal bonding in that carbon with its allotropes, has a range of crystalline structure that can resemble ceramic. Most engineered ceramic are covalently bonded and as such are not as easy to react with as other metals. For example, graphite is ‘partially covalently bonded” […]

Accomodating Thermal Expansion Mismatch

Metal fillers (solders and brazes) can join a wide variety of materials, including aluminum, copper, stainless steel, refractory metals with aluminum oxide, aluminum nitride, silicon carbide and other oxide, nitrides and carbides… However, the success of bonding ceramic to metals depends on the exact ceramic and metal materials and the joined assembly size and geometry.
