The Influence of the Tantalum Content on the Main Properties of the TixTa9Nb8Zr2Ag Alloy

This study presents the influence of different contents tantalum alloying elements on mechanical and electrochemical properties TixTa9Nb8Zr2Ag alloys their corrosion resistance in a 3% NaCl solution. These exhibit structure with more than 80% beta phase, Young’s modulus between 82 55 GPa close to human bone, good resistance, rate 5 47 μm y−1. Furthermore, excellent behavior alloy 10 15% content is highlighted, revealed by nobler potential, low rate, high passivation tendency The results reported this work allow us consider that titanium 10–20% Ta could be valid alternative for use orthopedic surgery, level can customized depending nature treated bone complexity difficulty implant machining, i.e., required optimum hardness.
