Description
Ti-Cu alloys are promising alloys for biomedical application in dentistry. Previously, metal ions (Ag+ and
Zn+) have been widely used as antibacterial agents, however these ions have been found to be toxic to
the human body [1]. Copper has been preferred as a good antibacterial agent due to its low toxicity and
high cytocompatibility. The current study is aimed at producing biocompatible Ti-Cu alloys with good
mechanical properties, corrosion resistance and antibacterial properties.
Methods
Several TiCu alloys were synthesized with the following composition: Cp-Ti, Ti-0.88wt.%Cu, Ti-
2.44wt.%Cu, Ti-3.24wt.%Cu and Ti-10wt.%Cu. The alloys were then exposed to staphylococcus
epidermidis bacteria. Then they were characterized using the scanning electron microscopy (SEM),
energy dispersive spectroscopy (EDS), scanning transmission electron microscopy (STEM), focused ion
beam SEM (FIBSEM) and transmission Kikuchi diffraction (TKD) technique.
Rsults of this study will be available during the date of the conference presentation
