🧩 Product Overview
The D Series Laboratory Vacuum Diffusion Bonding Furnace is a high-precision thermal processing system designed for solid-state bonding of materials under vacuum and controlled pressure.
This system enables:
- Diffusion Bonding (solid-state joining)
- Vacuum brazing
- Degassing and heat treatment
👉 Key capability:
- Joining materials without melting
- Achieving base-material-level joint strength
Diffusion Bonding is a solid-state process where materials are bonded under high temperature and pressure without visible deformation or melting, resulting in joints with properties similar to the base material
🔬 Working Principle (Diffusion Bonding Process)
The system operates using temperature + pressure + time under vacuum:
- Workpieces are placed in contact inside the chamber
- Vacuum removes oxidation and contamination
- Temperature rises to diffusion range
- Pressure is applied through pressing system
- Atomic diffusion occurs across the interface
👉 Result:
- Metallurgical bonding without melting
- No heat-affected zone
- Minimal deformation
Diffusion Bonding creates joints where microstructure and properties are similar to the base material, avoiding defects typical of fusion welding
