| Abstract Scope |
TiZrTaNb-based high-entropy alloys (HEAs) are considered for biomedical applications because of their good yield strength, hardness, promising wear resistance, and high corrosion resistance compared to traditional alloys. Their production through additive manufacturing allows for the creation of customized implants, effectively addresses significant design challenges, and enables microstructural adjustments. The manufacturing process and the resulting microstructure highly influence the corrosion mechanisms of different alloys under various conditions. This study explores the corrosion behavior of two HEAs with different compositions in simulated physiological environments. Adjusting the nominal composition can significantly impact the microstructure, the properties of the passive surface oxidation, and the extent and mechanisms of corrosion and metal release. The evaluation of the corrosion mechanism includes immersion tests and post-corrosion analysis using both conventional and synchrotron radiation techniques. The findings from this research enhance our understanding of additively manufactured TiZrTaNb-based high-entropy alloys, thereby increasing their potential for biomedical applications. |
