Abstract

In this work, the amorphous alloys Co₆₉Nb₂₃B₈, Fe₇₈Si₉B₁₃, Co₆₈Cu₂₃B₉ and Fe₆₄Nb₂₈B₈ were synthesized by high energy milling (HEM) and investigated as promising biomaterials for bone tissue regeneration. The amorphous alloys Co₆₉Nb₂₃B₈, Fe₇₈Si₉B₁₃, Co₆₈Cu₂₃B₉ and Fe₆₄Nb₂₈B₈, were milled using a load of 20 g, with a ball-to-powder weight ratio of 20:1, rotation speed 300 rpm, grinding time was 15 h, and used ethyl alcohol (C₂H₆O) as a process controlling agent (PCA) as a grinding medium and an argon atmosphere.  The amorphous alloys were subjected to characterization by XRD, FTIR, textural analysis, SEM, thermogravimetric analysis (TGA-DTA), magnetic measurements (VSM), mechanical tests and in vitro cytotoxicity tests.   Finally, it was observed through the cytotoxic profile that the safe concentration, at which cell viability was greater than 70%, had promising potential for applicability as a metallic biomaterial for bone tissue regeneration and temporary implants in orthopedics.
