Diffusion bonding of aluminium and aluminium alloys.

摘要

The present invention provides a process in which components made of aluminium or an alloy thereof can be diffusion bonded together; the process involves chemically treating the components to remove aluminium oxide on the surface of the components, subjecting them to grit blasting and to a second chemical oxide removal step and finally pressing the components together under heat until they form diffusion bonds. The resulting composite can be superplastically formed to shape.
