Gold makes tiatanium harder
“It is about 3-4 times harder than most steels,” said Emilia Morosan, from Rice University. “It’s four times harder than pure titanium, which is what’s currently being used in most dental implants and replacement joints,” said Morosan.
The atomic structure of the material – its atoms are tightly packed in a “cubic” crystalline structure that is often associated with hardness – was previously known.
However, Morosan and former graduate student Eteri Svanidze are first to document the remarkable properties of the ultra-hard “beta” form of the compound.
