可降解鋅基生物材料的研究進展可降解鋅基生物材料的研究進展Research Progress on Biodegradable Zinc-Based Biomaterials 鋅作為人體必需的微量元素,具有理論適中的降解速率和降解行為,因此在近年來,成為繼鎂合金與鐵合金后的一種新的可降解醫(yī)用植入材料。但由于鋅合金的設(shè)計、加工制備以及降解機理的研究剛處于起步階段,尚未形成系統(tǒng)性的研究成果。本文就目前可降解鋅合金的研究現(xiàn)狀及未來的研究方向進行綜述。 In recent years, zinc, as an essential trace element, with its alloys has attracted increasing attention as new biodegradable metals for because of its appropriate degradation rate and degradation behavior. In this stage, it appears that the fabrication and degradation mechanism of zinc alloys as biodegradable metal stills needs abundant systematic study. This review summarizes progress towards biodegradable zinc alloys. It emphasizes the current understanding of physiological and biological benefits of zinc and its biocompatibility. Finally, the review provides an outlook on challenges in designing zinc-based stents of optimal mechanical properties and biodegradation rate. 全文下載:https://pan.baidu.com/s/1pLSbNon
