S-Bond Technologies offers joining services for components that require graphite, graphite foams, pyrolytic carbon, carbon foams, carbides and diamond. The active elements in S-Bond alloys and our proprietary joining processes enable the joining of any metal to most carbon based materials in a wide range of applications
Our joining methods have the following characteristics:
• No flux , no filling of pores when joining foams.
• No plating required.
• Joins carbon based materials to most metals, ceramics and composites.
• Joints are made at lower soldering temperatures and can be reworked.
• S-Bond joining mitigates thermal expansion mismatch issues experienced in brazing.
S-Bond characteristics include:
• Alloy 220 joins from 250-270°C.
• Alloy 400 joins from 410-420°C.
• Thermally conductive, over 10 x that of filled epoxies
S-Bond Alloy 220 can wet (liquid spreading without balling up) and adhere to the surface of the graphite and graphite foams, carbides, carbon and diamond. After pre-treatment with S-Bond layers, the graphite / carbon / carbide based materials can be joined to electrical leads, metal face sheets or other types of metals and composite structures. When joining graphite foams, S-Bond alloys wet and encapsulate the Gr-foam webs, leading to adherence and gripping around the Gr-foam webs, thus creating strong and thermally conductive joints. S-Bond joining is an effective method for joining highly conductive graphite foams to metallic and composite face sheets.
S-Bond Technologies provides a range of versatile fabrication services to joining components such as:
- graphite foam core cold plates - graphite foam heat storage units
- thermal management devices - diamond or diamond composite heat sinks
- SiC armor plates - SiC based power electronic assemblies
- wear plates and surfaces - graphite conductors and feedthru's
