Corrosion and antibacterial performance of novel selective-laser-melted (SLMed) Ti-xCu biomedical alloys

Ti-xCu biomedical alloys were designed to have satisfactory antibacterial properties compared to pure Ti. Ti-xCu (x = 0, 3, 5, 7, and 10 wt%) alloys were prepared by selective laser melting (SLM) using powders of pure Ti and pure Cu. Increasing Cu content decreased the grain size, increased the amount and size of Ti2Cu particles, and increased the hardness. The electrochemical experiments revealed that Ti-5Cu had the best corrosion resistance,...
