Abstract
Biomaterials are attracting an ever-increasing research interest. As part of this overall effort, we report herein the fabrication and characteristics of Zr-based ribbon samples with three different compositions: Zr56Co28Ga16, Zr56Co28Ga14Si2, and Zr56Co28Ga14Sn2. The supercooled-liquid region ÎTâ¯=â¯Txâ¯ââ¯Tg of these materials is 16, 18, and 29â¯K, respectively, where Tx is the temperature of the onset of crystallization and Tg is the glass-transition temperature. The samples are thermally characterized by using differential scanning calorimetry and by determining the activation energy. The corrosion resistance is determined by immersing the materials for up to 20â¯days in a simulated body fluid, and the cytotoxicity is measured from the proliferation of osteoblast-like cells on the samples. Finally, the mechanical properties are investigated by nanoindentation. The Young's modulus is 112â¯GPa. These results all highlight the suitability of this metallic glass for biomedical applications.
