Advanced Plastic Processing Techniques for the Densification of Spray Deposited Preforms
In the present investigation, several novel techniques including sequential motion compaction, ceramic rolling and frame-confined rolling have been developed to improve the formability of spray deposited porous aluminum alloy preforms. The experimental results show that these techniques can greatly improve the workability of the spray deposited performs. Especially, sequential motion compaction can be used to densify the preforms of large dimensions which are difficult to further processing by the traditional techniques to fully dense.
