Welcome!

Welcome to this technical forum for ceramic-metal bonding. S-Bond Technologies is pleased to present and offer this technical discussion forum dedicate to the ceramic:metal bonding. Ceramic:metal bonding has been used extensively in industry anywhere from wear surfaces to electronics. With the increasing demands on materials and their performance in a host of applications including sensors, […]

Service Conditions and Ceramic: Metals Joint Behavior

177226931Ceramic:metal bonding is done in many applications from propulsion and turbine components, electronic packaging, electrical power components, batteries, sensors, sensor housings, wear inserts, medical surgical components, insulating feeds, etc. These varied applications also mean widely varying performance requirements and service conditions. This lead off discussion thread is to get us all thinking about performance and service and to present materials, design and commercial solutions that have been considered, used… offering case studies or other articles that permit our community insight into issues and solutions.

To get this discussion started I will highlight function and considerations in selecting ceramic:metal bonding.

Compatible Filler Metals for Joining Ceramic

When joining ceramic to metals a lot factors need to be considered… First is always the expected service environment, temperature and thermal cycling. Second is the ceramic and the metal materials being joined. And third, the size and geometry of the joint. Ceramic:metal bonding does require careful analysis of the chemistry of the materials and […]

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.
