" name="ChDivSummary">Biodegradable magnesium(Mg) alloy stents are the most promising next generation of bio-absorbable stents. In this article, we summarized the progresses on the in vitro studies, animal testing and clinical trials of biodegradable Mg alloy stents in the past decades. These exciting findings led us to propose the importance of the concept "bio-adaption" between the Mg alloy stent......
have been reported. Increasing the content of Al and Zn[2], reducing the content of Li[3], multi- element alloying[4] and composite reinforcement[5] will enhance the strength of Mg-Li alloy, but to some... the grain size to increase to some degree, which is the same as the effect of ZnO particles on the grain refinement of Mg-Zn alloy[9]. It is shown that an optimal addition level of Al-5Ti-1B exists......
of endothelial cells(ECs).To solve the main obstacles,an anti-corrosion and quick endothelialization coating was prepared on novel Mg-Zn-Y-Nd alloy via a simple two-step immersion method in the present study... for re-endothelialization.The results suggest that HF-PDA-treated Mg-Zn-Y-Nd alloy has great potential in the application of vascular stent and the surface coating method is of great application value......
and diffused into the liquid metal to form alloy in NaCl-KCl-MgCl2 melt at 750 ℃. LIN and UAN[5] proposed the preparation of Mg-Li-Al-Zn master alloy in air by electrolytic diffusing method at 500 ℃. AZ91...-deposition is another traditional method to produce alloy by electroplating and electrowinning[8-10]. However there is no report on the Mg-Al, Mg-Zn and Mg-Al-Zn alloy preparation through co-deposition method......
