Abstract:

Implementations are provided for fabricating a finished workpiece having a shaped portion. One implementation includes: a superplastic formation diffusion bonding (SPFDB) component; a cold spray additive manufacturing (CSAM) component; and a mold having a concavity. Various configurations can operate on a workpiece with the SPFDB and CSAM components in different orders. An implementation is configured to cold spray (with the CSAM component) an additive material onto the workpiece; and perform superplastic forming (with the SPFDB component) on the workpiece with the mold, thereby rendering the workpiece into the finished workpiece having the shaped portion. The shaped portion conforms to a shape defined by the concavity. Cold spraying results in an increased thickness of the finished workpiece in a target region, which can provide structural reinforcement, and which can have a tapered edge. The workpiece can be a metal substrate made of titanium, aluminum, stainless steel, or another material.
