| Abstract Scope |
To address the problems of antimicrobial resistance, considerable research effort was focused on exploring alternative approaches to conventional Ti implants. Recent advancements in the design of antibacterial Ti biomaterials include incorporating non-conventional metal antibacterial agents such as copper (Cu) and gallium (Ga), altering surface properties such as charge, and hydrophobicity by chemical modification, or engineering of the surface topography.
Considering that alloying with Ga and Cu on Ti-based alloys may lead to improved properties for bone-related implants, the purpose of this work is to evaluate the effects of these antibacterial elements on the structural characteristics, mechanical and electrochemical behaviour of novel Ti-Nb-Ga/Cu alloys.
These alloys combine the low modulus of the beta-single phase microstructure with antibacterial function of Cu and Ga ions, while maintain the others excellent properties of the Ti-alloys, like the high corrosion resistance and biocompatibility.
