“…During the diffusion bonding of materials, the interlayer of low melting point metal will melt and generate transient liquid phase that enhances bonding. The metals used for this inter-layer are copper, silver, etc [2][3]. However, all liquid phase bonding methods utilizing metal inter-layer directly increase the complexity and may decrease the bonding strength.…”

This paper presents a diffusion bonding technology at vacuum using a high-boiling liquid protection, diethylene glycol dimethyl ether (C6H19O3). After washing in alcohol, the specimens were immersed in diethylene glycol dimethyl ether. Before heating, the vacuum chamber was vacuumized to about 10-1Pa. Then chamber was heated to about 80°C, and held for 20 minute to evaporate the liquid protection in order to make the clean bonding surfaces contact. Metallographic observations of the interface by optical microscope were carried out. The experimental results show that the protections have successfully protected the bonding surfaces from re-oxidation prior to bonding. The metallographs show that the vacancies at the bonding interface bonding at 560°C for 2 hours are obvious and the materials at the interfaces of specimens bonded under the pressure of 5 MPa at 535°C for 2 hours were well joined.
