Vacuum Diffusion Bonding

Vacuum diffusion bonding refers to a welding method in which closely attached components are kept at a certain temperature and pressure for a period of time in a vacuum environment, so that atoms between the contact surfaces diffuse to each other to form a connection.

Although diffusion welding is a long-standing A historic welding process, but only in recent years has it developed rapidly. The weld seam of this process is invisible to the naked eye, and no brazing filler metal is added and no material is melted. Even at high magnification, it is difficult to observe the crystalline phase transition. The part properties of diffusion welding are also unique in terms of higher strength, best corrosion resistance, and no cross-contamination. Many new applications, including energy engineering, semiconductors, tooling and aerospace, are starting to be used for their many advantages. this special process.
