Production of Aluminum Foams with Ni‐coated TiH₂ Powder

Abstract

Aluminum foams produced from Ni-coated TiH2 display higher final densities than those produced with-out the Ni diffusion barrier; however, resulting foams display rounded pores and a narrower pore size distribution. The 1–2 μm Ni-coating layer is produced by an electroless technique, and is strong enough to remain attached to TiH2 after the mixing and compaction step in the powder metallurgical foaming process.
