Summary
A process for hot-press canning of unplated Th cores in Al jackets was developed using wafers of Th and Al for diffusion and bonding studies. Thorium wafers which were electroplated with Ni, Cu, or Fe-Ni and hot-pressed canned appeared to offer no advantages in uniforraity of diffusion or bond strength (the bases of the evaluation) over unplated thorium. Canning operations with full size unplated cores resulted in over half the canned assemblies being rejected because of unbonding between the core and jacket. Experiments which were run to determine the cause of the unbonding indicated that it was due to materials occluded in the Th core (apparently during fabrication) which volatilized during the canning openation.
