Article Citation - WoS: 1Sol-Derived Hydroxyapatite Ddip-Coating of a Porous Ti6al4v Powder Compact(Al-Farabi Kazakh State National University, 2009) Altındiş, Mustafa; Güden, Mustafa; Güden, Mustafa; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyA sintered porous Ti6Al4V powder compact with a mean pore size of 63 µm and an average porosity of 37±1% was dip-coated at soaking times varying between 1- and 5-minute using a sol-derived calcium Hydrooxyapatite (HA) powder. The coated compacts were heat-treated at 840 °C. The coating thickness was found to increase with increasing soaking time, from 1.87 µm at 1-minute soaking to 9 µm at 5-minute soaking on the average. It was shown that at increasing soaking times, the originally open pores started to close, while at low soaking times the Ti6Al4V particles were partially coated. The coating layer was shown to be nano porous and the depth of coating was observed to be relatively shallow: only few particles near the compact surface were HA-coated.Conference Object Open Cell Ti6al4v Foams for Biomedical Applications(Pamukkale Üniversitesi, 2006) Hızal, Alpay; Güden, Mustafa; Güden, Mustafa; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologySintered Ti6Al4V alloy foams were prepared using atomized spherical powders in the porosity range of 52-72 % using a space holder. Powder-space holder mixture was cold compacted at 200, 300,400, 500 and 700 MPa compaction pressures and then sintered at 1200 C for 2 h and 1300 C for 2, 4 and 6 h. The porosity level and mean pore sizes of the sintered foams were determined as function of the compaction pressure and sintering temperature and duration. The compression strength and deformation behavior of the foams were investigated.
