| Abstract Scope |
Titanium implants are susceptible to bacterial infection, necessitating excruciating and expensive revision surgeries. Copper as an antibacterial agent in the titanium alloying is an emerging, practical solution to this issue. This study aimed to investigate the synthesis of Ti-xCu alloys (x= 2.5, 5, and 10 wt.%) and assessed their dental application. Mechanical alloying was employed after optimizing milling parameters and followed by sintering and aging heat-treatment. The sintered Ti-xCu alloys were characterized to evaluate microstructure, phase composition, and thermal stability. The existence of Ti2Cu intermetallic phases, confirmed through structure and phase analyses, played a pivotal role in enhancing mechanical and corrosion properties. Hardness measurements revealed a substantial enhancement, increased from 185 for pristine Ti to 285 for Ti-10Cu alloy. Furthermore, Ti-5Cu and Ti-10Cu alloys revealed 69 and 71.5% improvement in the corrosion rate, respectively compared to α-Ti. This approach offers a practical and promising Ti-Cu alloy for dental applications. |
