COMPACTION AND SINTERING OF Ti AND Ti-6Al-4V PRODUCED FROM HYDRIDE-DEHYDRIDE POWDER

Abstract

Pure titanium and titanium alloys are widely used as implant materials in the medical and dental applications due to their superior bio-compatibility, corrosion resistance and specific strength compared with other metallic implant materials. Researchers in SIRIM Berhad have been investigating powder metallurgy techniques for producing fracture fixation plates. Hydride-dehydride titanium powders were compacted using simple press-and-sinter method, in order to find out if this route can be applied to produce the plates. Some part of work was done on Ti-6Al-4V (wt%) composition with irregular shape aluminium and vanadium powders. The preliminary study on green density, compaction pressure, sintering, outcome of density and hardness of sintered samples are presented. Two different plates are purchased and used as a reference to guide this research.
