Zr-based bulk metallic glasses (Zr-BMGs) are potentially the next generation of metallic biomaterials for orthopaedic fixation devices and joint implants owing to their attractive bulk material properties. However, their poor tribological properties and long-term biocompatibility present major concerns for orthopaedic applications. To this end, a novel surface modification technology, based on ceramic conversion treatment (CCT) in an oxidising medium between the glass transition temperature and the crystallisation temperature, has been developed to convert the surface of commercially available Zr44Ti11Cu10Ni11Be25 (Vitreloy 1b) BMG into ceramic layers. The engineered surfaces were fully characterised by in-situ X-ray diffraction, glow-discharge optical emission spectroscopy, scanning electron microscopy, transmission electron microscopy, and scanning transmission electron microscopy. The mechanical, chemical, and tribological properties were evaluated respectively by nano-indentation, electrochemical corrosion testing, tribological testing and the potential biocompatibility assessed by a cell proliferation assay. The results have demonstrated that after CCT at 350 °C for 40 h and at 380 °C for 4.5 h the original surfaces were converted into to a uniform 35–55-nm-thick oxide layer (with significantly reduced Ni and Cu concentration) followed by a 200–400-nm-thick oxygen-diffusion hardened case. The surface nano hardness was increased from 7.75 ± 0.36 to 18.32 ± 0.21 GPa, the coefficient of friction reduced from 0.5–0.6 to 0.1–0.2 and the wear resistance improved by more than 60 times. After 24 h of contact, SAOS-2 human osteoblast-like cells had increased surface coverage from 18% for the untreated surface to 46% and 54% for the 350 °C/40 h and 380 °C/4.5 h treated surfaces, respectively. The significantly improved tribological properties and biocompatibility have shown the potential of the ceramic conversion treated Zr-BMG for orthopaedic applications.

“…Metallic glasses (MGs), which are newcomers to the eld of amorphous materials, have attracted great interests due to their remarkable mechanical, physical, and chemical properties [1][2][3] . Their disordered atomic structures inherited from molten melts generate ultrahigh strengths, high elastic limits, low Young s moduli, good wear resistances, and excellent corrosion resistances, leading to comprehensive application potentials as structural and functional materials [4][5][6] .…”

Due to its good comprehensive mechanical properties and low cost, 45 steel has long been widely used for the manufacture of various components. However, the relatively low corrosion resistance of 45 steel has negative effect on its application and should be further improved. In this work, a Zr 50 Ti 5 Cu 27 Ni 10 Al 8 metallic glass (MG) coating was successfully obtained on 45 steel by laser cladding method. The microstructure and the morphology of the MG coating were also examined. Corrosion test indicated that the glass coated 45 steel exhibited much higher corrosion resistance than that of bare 45 steel. This is due to the alloying element Zr and the structurally and chemically homogeneous structure of MG coating.

Influence of Oxidation on Structure, Performance, and Application of Metallic Glasses

Owing to their unique structure and outstanding properties, metallic glasses are a novel class of structural and functional materials with vast application prospects. However, the metastable amorphous structures and chemical activity of metallic glass constituent elements lead to frequent oxidation during preparation, processing, and application. Comprehensively understanding the oxidation behaviors and underlying mechanisms of metallic glasses is essential for gaining knowledge of metallic glass structures and properties and for promoting engineering applications. Although many studies have examined these issues, more investigations are still required to explore potential industrial applications of metallic glasses. Here, recent research on metallic glass oxidation is consolidated by summarizing the oxidation influence on metallic glass structure, performance, and application and the possibilities and feasibility of oxidizing metallic glasses to reinforce materials or develop material systems are discussed.
