A diffusion bonding furnace includes a pressure vessel having a top and a chamber. A press penetrates through an opening in the top of the pressure vessel, so that a first end of the press is disposed within the chamber. The opening in the top of the pressure vessel is sealed around the press to prevent leakage when the pressure vessel is at a pressure other than atmospheric pressure. A moveable bolster is secured to the first end of the press and a moveable platen is attached to the moveable bolster.

Diffusion bonding furnace having a novel press arrangement

A heat treating furnace has a hot zone enclosure with a substantially rectangular cross section. The floor of the hot zone enclosure is formed such that it is removable independently of the remainder of the hot zone enclosure. The heat treating furnace has a heating element with a novel support element that is readily mounted on and removed from the hot zone enclosure and which adjusts to accommodate a wide range of heating element thicknesses and insulation shield thicknesses. The electrically insulating components of the support element are formed to resist electrical shorting resulting from metallization and to resist cracking from thermally induced stress. The heat treating furnace further includes a cooling gas injection nozzle formed to reduce turbulence in the injected gas stream and to be readily attached to or removed from the hot zone enclosure. The gas injection nozzle is preferably formed of a ceramic material and is mounted in an opening in the hot zone enclosure by a very coarse, light-bulb-like, thread formed in the body of the gas nozzle.
