GS14 Fabrication of Porous Titanium by Friction Powder Compaction Process

Abstract

Open-cell porous titanium (Ti) was fabricated by friction powder compaction (FPC) process, which requires no external heat sources. In this process, a mixture of Ti powder and sodium chloride (NaCl) powder as spacer particle was used as starting materials. The powder mixture was compacting only by rotating tool plunged into the mixture. NaCl was removed by placing the sintered mixture in water, and pores were formed. Porous Ti with porosities of 57.9 % was successfully fabricated. In this study, pore structures of obtained porous Ti were nondestructively observed by X-ray computing tomography (CT).
