Characterisation of Titanium Foams Sintered at Different Temperatures Prepared by the Slurry Method

The mechanical and physical propertics of titanium foam sintered at different temperatures are reported in this paper. In this work, the slurry method has been used for the production of titanium foams using pure titanium and titanium alloy (Ti6Al4V). The titanium slurry was first prepared by mixing...

In this work, the slurry method has been used for the production of titanium foams using pure titanium and titanium alloy (Ti6Al4V). The titanium slurry was first prepared by mixing the titanium powder, polyethylene glycol (PEG), methylcellulose and water. Polyurethane (PU) foams, which acted as scaffolds were then impregnated in the slurry, followed by drying at room temperature. These were later sintered in a high temperature vacuum furnace at 1200oC, 1250oC and 1300Â°C. The resultant titanium foams were characterised using Scanning Electron Microscopy (SEM) and the compressive strength test. The range of pore sizes obtained was between 388 Âµm to 1.07 mm, with a strut size in the range of 59.4 Âµm to 227 Âµm. The highest compressive strength obtained was 14.85 MPa. This was for the titanium alloy foam which had been sintered at 1250Â°C. The highest density (1.25 g/cm3) obtained was for the pure titanium foams that were sintered at 1300Â°C. For these, the porosity was found to be 65.05%. In general however, the most suitable sintering temperature was found to be 1250Â°C for both the pure titanium and titanium alloy UKM 2010-02 Article PeerReviewed application/pdf en http://eprints.utm.my/id/eprint/9779/2/sains_malaysiana_feb_2010.pdf Ahmad, Sufizar and Muhamad, Norhamidi and Muchtar, A. and Sahari, J. and Jamaludin, Khairur Rijal and Ibrahim, M.
