| Abstract: | Metallic glass possesses characteristics such as high strength, excellent corrosion resistance, and outstanding biocompatibility, making it highly promising for wide-ranging industrial applications. In this paper, we fabricated three types of bionic anti-friction surface structures (wave-array structure, line-array structure, point-array structure) on zirconium-based bulk metallic glass (Zr-BMG). We used ball-on-disk friction and wear tests to evaluate the anti-friction properties of the surface-structured Zr-BMG at different temperatures. The results show that the bionic anti-friction surfaces exhibited evident anti-friction behavior at room temperature (273 K). The point-array structure on the Zr-BMG surface exhibits the best friction-reducing effect at 273 K. As the temperature increased to 473 K, the coefficient of friction (COF) on Zr-BMG surfaces decreased significantly with the increase of adhesive wear. At the same time, the friction-reducing effect of surface structures decreased. When the temperature rose to near the glass transition temperature (623 K), the structured Zr-BMG surfaces exhibited friction-enhancing behavior. The point-array structure demonstrates the best friction-reducing effect at room temperature and 473 K, and exhibits similar friction and wear characteristics to polished surfaces near the glass transition temperature (623 K). The point-array structure on the Zr-BMG surface provides a broad range of friction-reducing operating temperatures. This study offers theoretical references and data support for the preparation and application of friction-reducing surfaces on amorphous alloy components. [ABSTRACT FROM AUTHOR] |
