Metallisation
Precision metal coatings on ceramic substrates for electronics, sensors, and advanced engineering applications
Advanced Ceramic Metallisation
Henson Ceramics Limited has an in-house metallisation facility for the bonding of molybdenum and moly/manganese to alumina ceramic under high temperature, controlled atmosphere conditions which subsequently allows the ceramic to undergo conventional brazing to form a vacuum-tight ceramic to metal bond.
Such components are used in high power applications, for example, and others which require good electrical insulation, high thermal shock resistance, high mechanical strength, and good vacuum integrity.
HCL manufactures all of its inks and coatings in-house, making it possible to cater for almost any specialist coating application. Facilities are also available for the bonding of silver, platinum, gold, chrome, nickel, and a variety of cermets to the entire range of ceramics.
Technical Capabilities
Metal Options
Wide range of metallisation materials:
- Molybdenum and Moly/Manganese
- Gold, Silver, Platinum
- Chrome and Nickel
- Cermets and composite coatings
Deposition Techniques
Advanced deposition methods:
- Banding
- Electroplating
