Ceramic-to-Metal Sealing Technology
X-ray tube components operate under demanding combinations of high voltage, high vacuum, thermal cycling, and electrical insulation requirements.
TecCera uses high-temperature molybdenum-manganese metallization to prepare alumina ceramic surfaces for reliable metal joining.
Typical manufacturing processes include:
- Alumina ceramic forming
- Precision ceramic machining
- High-temperature Mo-Mn metallization
- Nickel, copper, or gold plating
- Precision metal machining
- Vacuum brazing
- Ceramic-to-metal sealing
- Dimensional and sealing inspection
This process enables strong and reliable ceramic-to-metal interfaces for X-ray tube and other vacuum electronic assemblies.
