Vacuum Diffusion Bonding Process

In vacuum diffusion bonding, the metal parts to be joined are first placed in a vacuum chamber to create a vacuum environment. The metal is then heated above its melting point by a heating system to partially or completely melt it. Next, vapor is generated on the surface of the molten metal, and the vapor molecules diffuse freely in the vacuum.


Quantity:

The vacuum diffusion bonding process has the following advantages:
1. Improve connection strength: Combining vacuum diffusion welding and other connection methods can achieve stronger connection strength.
2. Reduce porosity and defects: the vacuum environment can effectively remove gas and impurities, thereby reducing the generation of porosity and defects.
3. Improved connection quality: By combining different connection methods, higher quality connections can be obtained with better mechanical properties and corrosion resistance.
4. Expand the scope of application: Vacuum diffusion bonding can be applied to the connection of different materials, including metals, ceramics and non-metallic materials.

Vacuum diffusion bonding technology is widely used in the fields of aviation, aerospace, energy and industrial manufacturing, and can meet the high requirements for connection quality, strength and reliability.


Vacuum diffusion welding has many advantages, such as high welded joint strength, no pores, no defects such as solutes and mechanical impurities. In addition, due to welding in a vacuum environment, oxidation and pollution can be avoided
Further improve the welding quality. This makes vacuum diffusion welding widely used in aerospace, electronics, semiconductor, optics and other high-precision fields.
