Bulk metallic glasses (BMG) are a promising candidate for biomedical
applications due to their properties of high strength, high hardness, relatively
low Youngs modulus, high elastic and good resistance to corrosion.
Among the various types of BMG, those based on Zr have attracted the greatest
research interest for their base element Zr, which presents a good resistance to
wear and biocorrosion that offers a long life and a low release of ions; what
makes it a highly biocompatible element.
The objective of this research work is to obtain and characterize amorphous
ribbons of the Zr58Co21Al9Ag12 system. Using a chill block melt spinning
casting process (CBMS), 3 types of ribbons were obtained under different
processing conditions varying the speed of the cooling disk and the diameter of
the crucible, obtaining ribbons with thicknesses of 80-150μm. They presented a
portion of crystalline phase for the 3 conditions used, the degree of
amorphization being greater for the smaller diameter crucible used during the
casting process in chill block melt spinning.
The structure of the obtained ribbons was verified by x-ray diffraction (DRX,
Bruker D8), the chemical homogeneity was examined by scanning electron
microscopy (MEB, JEOL JSM-7600F), the thermal analysis was performed using
differential scanning calorimetry ( DSC, TA Instruments SDT Q600).
