摘　　要：医用无镍不锈钢比传统不锈钢具有更加优异的综合性能,在骨组织和血管修复等医疗器械领域中具有广阔的应用前景。近些年无镍不锈钢作为医用金属材料的优异性能正在被逐步挖掘,这对开发具有更高服役安全性和生物相容性的医疗器械具有重要意义。本文主要综述了无镍不锈钢在合金设计、力学性能、耐蚀性和生物相容性方面的研究进展以及产品开发现状,展望了这一新型医用金属材料的未来发展趋势。Biomedical nickel-free stainless steels acquire better comprehensive properties than the traditional stainless steels, with wide application prospect in medical devices for bone and vascular repair. As a new biomaterial, in recent years, the excellent properties of nickel-free stainless steels are gradually verified, which is meaningful for developing medical devices with higher safety and biocompatibility.In this paper, the research progress on alloy design, mechanical properties, corrosion resistance and biocompatibility of nickel-free stainless steels and the current application status are reviewed, and the future tendency on research and development for this new metallic biomaterial is also proposed.
