“…A possible way to address this issue is to take the inspiration from the structure of a natural bone and introduce porosity into the BMG substrate, i.e., the foamed BMG. [24][25][26] Porosity will also improve osseointegration and implant stabilization with the adjacent tissue. It has been suggested that porosity throughout the entire implant structure could reduce the stiffness of the material, which further addresses the stress shielding issue.…”

Bulk metallic glasses (BMGs) represent an emerging class of materials that offer an attractive combination of properties, such as high strength, low modulus, good fatigue limit, and near-netshape formability. The BMGs have been explored in mechanical, chemical, and magnetic applications. However, little research has been attracted in the biomedical field. In this work, we study the potential of BMGs for the orthopedic repair and replacement. We report the biocompatibility study of zirconium (Zr)-based solid BMGs using mouse osteoblast cells. Cell attachment, proliferation, and differentiation are compared to Ti-6Al-4V, a well-studied alloy biomaterial. Our in-vitro study has demonstrated that cells cultured on the Zr-based BMG substrate showed higher attachment, alkaline phosphatase activity, and bone matrix deposition compared to those grown on the control Ti alloy substrate. Cytotoxicity staining also revealed the remarkable viability of cells growing on the BMG substrates.

“…A secondary fixation was performed by incubating the samples in 2 pct osmium tetroxide in 0.1 M cacodylate for 1 hour. The cells were then dehydrated by replacing the buffer with increasing concentrations of ethanol (25,50,70,95, and 100 pct) for 10 minutes each. Samples were then critical point dried and sputter coated in gold.…”

“…Although some research works have discussed the multiplestage parabolic rate law and ionic diffusion phenomenon during BMG oxidation [13][14][15][16], few attentions have been paid to the relationship between crystallization and oxidation kinetics. Also, detailed investigations on the effects of thermal parameters on surface morphology evolution especially the segregation phenomena are still lacking.…”

“…They may have great promise as structural material due to their great strength, high hardness, and favorable resistance to wear and fatigue, but metallic glasses are often devoid of ductility, which severely limits their use in traditional engineering applications [2].

“…

Porous metals are used for structural purposes in some cases, and for functional purposes in other cases based on their different specific structural morphologies and properties [1]. They may have great promise as structural material due to their great strength, high hardness, and favorable resistance to wear and fatigue, but metallic glasses are often devoid of ductility, which severely limits their use in traditional engineering applications [2]. Generally, porous metals have an integrative advantage over other porous materials in their physical and mechanical properties, which include electrical or thermal conductivity, stability at high or low temperatures, thermal shock resistance to temperature variations, strength, toughness, and the ability to resist impact force.
