摘　　要：在生物可降解金属材料方面,人们对镁基和铁基合金进行了广泛的研究,但是在力学性能、生物相容性和体内降解速率三个方面很难表现出令人满意的组合。近年来,生物可降解锌合金因其独特的生物降解可控及生物兼容性而备受学者青睐。综述了生物锌合金的生物毒性、生物相容性、加工工艺、力学性能和生物腐蚀性能方面的最新研究进展,并讨论了合金化、加工工艺在生物锌合金强韧性和生物腐蚀性兼具上的局限性,提出了生物可降解锌合金制备的未来发展趋势。In terms of biodegradable metal materials,magnesium-based and iron-based alloys have been extensively studied,but it is difficult to show a satisfactory combination of mechanical properties,bio-compatibility and in vivo degradation rate.In recent years,biodegradable zinc alloys have been favored by scholars due to their unique bio-degradation controllability and bio-compatibility.The latest research progress in bio-toxicity,bio-compatibility,processing technology,mechanical properties and bio-corrosion properties of bio-zinc alloys has been reviewed,while the alloying and processing technology on the combination of strength,toughness and bio-corrosion of bio-zinc alloys have been discussed.The limitations of biodegradable zinc alloy preparation have been proposed in the future.
