Description

Recently, titanium-tantalum alloys have been studied as implant materials for dental and orthopedic surgery. For alloys used in a living body, it is essential to have biological characteristic such as being nontoxic and compatible with living tissue and dynamic characteristics such as high durability. It is well known that titanium and tantalum are difficult to use in alloys made in the more common melting furnaces, which are arc melting and induction melting, because titanium and tantalum have great differences in melting points and density (Ti:1, 680℃/4.5g/cm3, Ta:2, 990℃/16.6g/cm3).In addition, titanium and tantalum are very reactive metals. To make a Ti 85wt%-Ta 15wt% binary alloy, the Cold Crucible Levitation Melting (CCLM) method which is one of the induction melting furnaces is good for making this type composition. The CCLM apparatus consists of a water-cooled crucible made from oxygen-free high purity copper segments and coil wrapped around the crucible and connected toa frequency inverter power supply. We have successfully made 1.0kg of uniform composite Ti 85wt%-Ta 15wt% binary alloy with the CCLM furnace. This result shows that the CCLM furnace is very useful for obtaining a Ti-Ta binary alloy despite the great difference in specific gravity.
