Ceramic Brazing with Mo-Mn Metallization

Mo-Mn metallization creates a controlled metallic layer on the ceramic surface before the brazing operation. This approach is widely used when the assembly requires high bonding reliability and hermetic ceramic-to-metal sealing.

Key Features

  • Mo-Mn ceramic metallization
  • Nickel plating compatibility
  • Reliable filler-metal wetting
  • High hermeticity potential
  • Suitable for demanding environments

Process Structure

A typical production sequence includes ceramic cleaning, Mo-Mn coating, high-temperature metallization, nickel plating, component assembly, brazing, and final inspection.

Why It Matters

Ceramics are difficult for conventional filler metals to wet directly. The metallized layer creates a more suitable interface between the ceramic and brazing filler metal.

Applications

Common applications include vacuum feedthroughs, electronic packages, high-voltage insulators, X-ray components, semiconductor equipment, and hermetic assemblies.

Custom Metallization

If your project specifies metallization thickness, nickel plating, or brazing filler requirements, send the specification for process evaluation.
