Production of Aluminum Foams with Ni-coated TiH2 Powder

Production of Aluminum Foams with Ni-coated TiH2 Powder

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 e...

Zusammenfassung: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.
