Method For Diffusion Bonding Workpieces And Article Fabricated By Same
US Patent:
4350528, Sep 21, 1982
Filed:
Jun 12, 1980
Appl. No.:
6/158761
Inventors:
Edgar W. Engle - Rogers AR
Assignee:
TRW Inc. - Cleveland OH
International Classification:
B22F 702
US Classification:
75203
Abstract:
A diffusion bonding method for assembling members formed from a liquid phase system material into a monolythic structure free of flaws and distortion. Member blanks are first formed from the material as by compacting or the like and then sintered to have their full density and hardness characteristics. Following sintering, any special surface or internal features are machined into the blanks to define the members. The members are also provided with bonding surfaces adapted to be placed in mating engagement with each other. The members are placed in an assembled relationship with the bonding surfaces engaging each other to define a bonding zone. In some cases, it may also be desirable to place a weight on the assembled members to continuously urge the bonding surfaces toward engagement. In the actual bonding step, the members are heated in a vacuum environment to a temperature intermediate the melting temperatures of the material low and high melting phase components. During such heating, the liquid phase system material of the two members coalesce across the boundary zone to effect an integral joint or bond.
