Apatite forming and hydroxyapatite ceramics bonding ability of titanium (Ti)-based bulk metallic glasses (Ti40Zr10Cu 36Pd14 and (Ti0.40Zr0.10Cu 0.36Pd0.14) 99Ca1: BMGs) were investigated as a new type of biomaterials. Powder mixture of CaHPO 4·2H2O and Ca(OH)2 and the BMGs disks were treated with autoclave for hydrothermal hot-pressing (HHP) simultaneously (150°C, 40 MPa, 2hours). Direct bonding hydroxyapatite ceramics and both type of BMGs could not be achieved. And then, the BMGs disks with the HHP treatment were soaked in simulated body fluid for 7-10 days. It was observed that apatite are deposited and covered on the surface of the BMGs with the HHP treatment. It was firstly demonstrated that surfaces of Ti based bulk metallic glasses can be made bioactive and that HHP techniques were useful methods in purpose of making Ti-based bulk metallic glass surface bioactive.
