Apr 08, 2017 · Today we will learn about diffusion bonding principle, working, application, advantages and disadvantages. Diffusion bonding is a solid state welding process in which, no liquid or fusion phase involves and the weld joint is form in pure solid state.
Apr 14, 2017 · One of the many vacuum processes to take note of today is that of diffusion bonding (aka diffusion welding or thermo-compression bonding). This technology, although highly specialized, continues to gain in popularity with design engineers and is finding more applications throughout manufacturing.

Vacuum Diffusion Bonding High Integrity Bonding. Vacuum diffusion bonding is a process whereby separate parts are joined without the use of filler metal. Vacuum diffusion bonding relies on temperature, pressure, time, and a very clean atmosphere (vacuum) to create the bond.
HIP diffusion bonding is used to create a usually solid state bond between two or more materials (either solid or powder) in contact with each other without adhesive, allowing for higher service temperatures and a stronger metallurgical bond.

3. Diffusion welding of samples The samples were welded in vacuum furnace from the company PVA TePla. This is high vacuum system with cold wall and integrated pressing unit and power-regulated resistance heater elements for application of the diffusion welding. Maximal pressing force is 1 500 kN
May 11, 2017 · Experience, innovation and customer focus are the basic components of this article on vacuum furnace diffusion bonding.Intuitive studying, based on physical concepts and technical testing, has led to an innovative solution for vacuum furnace equipment.
vacuum degree, 470 °C bonding temperature and 90 min bonding time; both bonding temperature and time are the main influence factors on as-extruded AZ91 magnesium alloys diffusion welding. Then the diffusion welded specimens were annealed, and the shear strength of joints was further improved to 76.93 MPa.
furnaces used for diffusion welding because of the compromises (sliding seals, etc.) needed for most Gleeble work, but sufficient for the present work. Vacuum hot press diffusion welding was also performed as part of the present work; stacks of Alloy 800H material meant to approximate the geometry of compact heat exchangers are shown in Fig. 3.
