The Effect of TiH₂ Oxidation Treatment on Preparing Aluminum Foam Sandwiches

Abstract:

Aluminum foam sandwiches (AFS) were successfully prepared by a powder metallurgical method. TiH₂powders were pre-treated in air at 450°C and 500°C for 2h in order to clarify the effect of oxidation treatment on AFS in comparison to those as-received. The decomposition curves of as-received and oxidized TiH₂ powders were monitored using DSC. The macro-morphology, expansion ratio, interfacial bonding and cell structure of AFS were systematically investigated. The results show that the AFS utilize TiH₂ powders oxidized in air at 450°C for 2h exhibits the best performance, under which conditions the effective bonding between the panel and core, 200% of the expansion rate and uniform pore structure of AFS have been achieved.
