Abstract
The present study investigates the Zr47Cu40Al8Ag4Dy1 bulk metallic glass (BMG) as a potential biomedical implant material, analysing its structural, mechanical, and corrosion properties. The synthesized rod by copper mold suction casting exhibited a fully amorphous structure, confirmed by X-ray diffraction and high-resolution transmission electron microscopy. Nanoindentation tests showed high hardness (~ 12.78 GPa) and low elastic modulus (~ 88 GPa), suggesting mechanical properties comparable to human bone, which could reduce the stress shielding effect. Nanoindentation analysis also revealed significant elastic recovery (69%) and resistance to plastic deformation from shear banding, essential for maintaining structural integrity under physiological environments. Creep and viscoelastic behaviour analysis confirmed time-dependent deformation, indicating suitability for long-term use for biomedical applications. Corrosion resistance is evaluated using electrochemical polarization tests in different simulated body fluids (SBFs), including phosphate-buffered saline (PBS), artificial saliva solution (ASS), and Hank’s balanced saline solution (HBSS). PBS provided the highest corrosion resistance, while HBSS has the least corrosion resistance.
期刊介绍:
The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials.
