TI-ZR-TA-AG BIOALLOY FOR ORTHOPAEDIC IMPLANTS

摘要

The invention relates to a Ti-Zr-Ta-Ag bioalloy for orthopaedic implants. According to the invention, the bioalloy consists of 73% titanium, 20% zirconium, 5% tantalum and 2% silver, the percentage being expressed by mass, and it has the maximum strength and flowing limit higher than pure titanium and the elasticity modulus value E of 59.62 GPa very close to the E value of human bone.
