Data for: Effect of Ti2Cu precipitation on antibacterial property of Ti–5Cu alloy

Michelle Oyen Editor-in-Chief Materials Science and Engineering: C Dear Editor: I wish to submit a research paper for publication in Materials Science and Engineering: C, titled “Effect of Ti2Cu precipitation on antibacterial property of Ti–5Cu alloy.” The paper was coauthored by Ju-Hui Wu, Chih-Yeh Chao, and Yen-Hao Chang. This study set out to examine the antibacterial effects of Ti alloys to which Cu had been added. We found that the solid-solution treatment of a Ti–5Cu alloy failed to provide an acceptable level of antibacterial activity, but the presence of nano-scale Ti2Cu precipitates led to the alloy exhibiting a relatively high antibacterial activity of > 90%. We believe that our study makes a significant contribution to the literature because this would provide a means of overcoming the serious problem of bacterial infection that remains an issue with the implantation of Ti prostheses. Further, we believe that this paper will be of interest to the readership of your journal because the relationship between heat treatment and the antibacterial property has not been explored in Ti based antibacterial materials. The aim of this work is to study the effects of heat treatment on microstructure and antibacterial property of a Ti-5Cu alloy in order to produce an optimal antibacterial material for clinic application. This manuscript has not been published or presented elsewhere in part or in entirety and is not under consideration by another journal. We have read and understood your journal’s policies, and we believe that neither the manuscript nor the study violates any of these. There are no conflicts of interest to declare. Thank you for your consideration. I look forward to hearing from you.
