Influence of Sr and Cu elements on the glass-forming ability and corrosion performance of Ca-based biomedical materials
Source abstract
Abstract
Ca-based bulk metallic glasses (BMGs) have attracted significant attention due to their high strength, low elastic modulus, excellent corrosion resistance, and good biocompatibility. However, their limited glass-forming ability (GFA) and difficulty in precisely controlling the degradation rate restrict their potential for clinical applications. In this study, we investigated the effects of adding different amounts of Sr and Cu on the GFA, corrosion behavior, and cytocompatibility of Ca 63 Mg 20 Zn 17 alloy. The results showed that the addition of Sr decreased the GFA of the alloy but enhanced its corrosion resistance. In contrast, the addition of Cu improved the GFA and corrosion resistance to some extent, but the performance decreased when the Cu content exceeded 1 at. %. Cytotoxicity tests indicated that all the alloys exhibited good biocompatibility and were non-toxic to cells. This study provides a theoretical basis for the application of Ca-based BMGs in biomedical materials and offers scientific support for the development of novel degradable implant materials.
