Abstract

Developing high-performance β-Ti alloys is a persistent and long-term demand for the advancement of next-generation biomaterials. In this study, a strategy of leveraging the unique characteristics of laser powder bed fusion (L-PBF) technique and nanocarbon materials was proposed to design a novel carbon-supersaturated β-Ti alloy. Ultrathin graphene oxide (GO) sheets were closely covering onto spherical Ti-15Mo-5Zr-3Al (Ti1553) powders, enhancing laser absorptivity while maintaining good flowability. Consequently, the GO-added Ti1553 builds tended to be denser than the initial ones, indicating an improved additive manufacturability. During L-PBF, GO sheets were completely dissolved into the Ti1553 matrix, generating fully carbon-supersaturated β-Ti structures with a reduced grain size. Thanks to the exceptional strengthening effects of high-concentration solid-solution carbon (∼0.05 wt%), the GO/Ti1553 builds achieved a high ultimate tensile strength of 1166 MPa. Moreover, as revealed by the immunofluorescence staining experiments, the GO/Ti1553 builds demonstrated a retained cytocompatibility. This study provides new insight into composition and processing design of high-performance Ti components for biomedical applications.

用于生物材料应用的碳过饱和 β-Ti 合金激光快速成型技术
开发高性能的β-钛合金是下一代生物材料发展的长期需求。本研究提出了一种利用激光粉末床熔融(L-PBF)技术和纳米碳材料的独特特性来设计新型碳过饱和β-钛合金的策略。超薄氧化石墨烯(GO)薄片被紧密覆盖在球形 Ti-15Mo-5Zr-3Al (Ti1553)粉末上,在保持良好流动性的同时提高了激光吸收率。因此,添加了 GO 的 Ti1553 构件往往比初始构件更致密,这表明添加剂的可制造性得到了改善。在 L-PBF 过程中,GO 片完全溶解到 Ti1553 基体中,生成了晶粒尺寸减小的全碳过饱和 β-Ti 结构。得益于高浓度固溶碳(0.05 wt%)的特殊强化效果,GO/Ti1553 构建物的极限拉伸强度高达 1166 兆帕。此外,免疫荧光染色实验表明,GO/Ti1553 构建材料具有良好的细胞相容性。这项研究为生物医学应用中高性能钛成分的组成和加工设计提供了新的视角。
