“…Such a low dpa is unlikely to introduce crystallization, which has been experimentally validated by GIXRD ( Figure S2). This is in agreement with prior studies on Ar-or N-ion implantation to Zr-and Ti-based BMGs where the amorphous structure was observed after implantation using XRD and transmission electron microscopy (TEM) [24,31]. Although the long range atomic ordering was not introduced after ion implantation, the short range ordering on the BMG surface could be altered due to the ion collision cascades.…”

“…Surface engineering techniques have been widely utilized to modulate surfaces of traditional biomedical alloys to endow bioactivity [18][19][20]. Bearing the similar concept, a number of surface engineering methods have been exploited to modify surface properties of BMGs, including micro-arc [21], coating [22], ion implantation [23,24], and so forth.…”

In the present study, low energy ion implantation was employed to engineer the surface of a Zr-based bulk metallic glass (BMG), aiming at improving the biocompatibility and imparting bioactivity to the surface. Ca- or Ar-ions were implanted at 10 or 50 keV at a fluence of 8 × 10(15)ions/cm(2) to (Zr0.55Al0.10Ni0.05Cu0.30)99Y1 (at.%) BMG. The effects of ion implantation on material properties and subsequent cellular responses were investigated. Both Ar- and Ca-ion implantations were suggested to induce atom displacements on the surfaces according to the Monte-Carlo simulation. The change of atomic environment of Zr in the surface regions as implied by the alteration in X-ray absorption measurements at Zr K-edge. X-ray photoelectron spectroscopy revealed that the ion implantation process has modified the surface chemical compositions and indicated the presence of Ca after Ca-ion implantation. The surface nanohardness has been enhanced by implantation of either ion species, with Ca-ion implantation showing more prominent effect. The BMG surfaces were altered to be more hydrophobic after ion implantation, which can be attributed to the reduced amount of hydroxyl groups on the implanted surfaces. Higher numbers of adherent cells were found on Ar- and Ca-ion implanted samples, while more pronounced cell adhesion was observed on Ca-ion implanted substrates. The low energy ion implantation resulted in concurrent modifications in atomic structure, nanohardness, surface chemistry, hydrophobicity, and cell behavior on the surface of the Zr-based BMG, which were proposed to be mutually correlated with each other.

“…Addition of minor element such as Ag, Cu, Y, Ti, Ni, and Nb has been utilized to enhance the glass forming ability and resistance to general and local corrosion. Inoue and coworkers [6][7][8][9][10] have investigated the effect of Ni on the corrosion resistance of Zr-NiCu-Al alloy. Zr-MG without Ni shows lowest corrosion potential and no obvious passivation region, but pitting directly can be observed as potential rises.…”

Metallic glasses exhibit excellent corrosion resistance and electrocatalytic properties, and present extensive potential applications as anticorrosion, antiwearing, and catalysis materials in many industries. The effects of minor alloying element, microstructure, and service environment on the corrosion resistance, pitting corrosion, and electrocatalytic efficiency of metallic glasses are reviewed. Some scarcities in corrosion behaviors, pitting mechanism, and eletrocatalytic reactive activity for hydrogen are discussed. It is hoped that the overview is beneficial for some researcher paying attention to metallic glasses.

Potential Prospective Application of Zr-Based Bulk Metallic Glasses in Dental Implant

Zr-based bulk metallic glasses (BMGs) are being studied widely in recent years due to their unique mechanical properties. In this paper, we will present the progress in the studies of corrosion resistance behavior and biomedical potential of the Zr-based BMGs, especially the in vitro and in vivo evaluation of their biocompatibility. Owing to their high resistance to corrosion in a physiological environment and the excellent biocompatibility that give them a passive, stable oxide film, Zr-based BMGs are considered the material of choice for intraosseous use. The aim of this paper is to give an overview of the available literature on the Zr-based BMGs and present a promising prospect for the application of oral implant.
