In Vitro Corrosion Resistance and Antibacterial Performance of Novel Fe?xCu Biomedical Alloys Prepared by Selective Laser Melting

Antibacterial Fe?xCu biomedical alloys were designed to have a satisfactory biodegradation rate compared to pure iron. Fe?xCu (x = 0, 1.5, 2.3, 7.8, and 10.1 wt.%) alloys were produced by selective laser melting (SLM). Alloying with Cu had a signi?cant influence on the grain size, hardness, biodegradation rate, and antibacterial performance of SLMed Fe?xCu alloys. Increasing Cu content decreased the grain size and increased the hardness. SLMed Fe?1.5Cu, Fe?2.3Cu and Fe?10.1Cu had degradation rates similar to that of pure iron, whilst the degradation rate of SLMed Fe?7.8Cu was almost 2.5 times faster. The SLMed Fe?2.3Cu, Fe?7.8Cu and Fe?10.1Cu produced strong antibacterial performance. The mechanisms of degradation behavior and antibacterial performance were clarified. SLMed Fe?7.8Cu had appropriate mechanical properties, satisfactory degradation rates, strong antibacterial performance and good cytocompatibility, and therefore was a novel type of antibacterial biomedical alloy with good potential for clinical application.This article is protected by copyright.
