| Abstract Scope |
In this work, we design a new Ti-Zr-Nb-Ta-based High Entropy Alloy (HEA) for bioimplants applications by combining the concept of HEA with biomaterial properties. The designed HEA was processed using powder metallurgy. The structure, microstructure, density, microhardness, and modulus of elasticity were investigated. The performance of the developed HEA was assessed by measuring its in vitro corrosion properties in simulated body fluid and artificial saliva. The antibacterial properties were compared to Ti6Al4V alloy and CPTi. The structure, microstructure, mechanical, and corrosion properties were discussed and correlated with the processing parameters. The results showed that the developed HEA has higher hardness, lower elastic modulus, and enhanced corrosion protection in simulated mediums, and antibacterial properties make it potential for bioimplant applications.
