Keynote 2: Investigations of local corrosion processes on biodegradable magnesium alloys using a novel online micro-flow capillary plasma mass spectrometer set-up with electrochemical control

Andrea Ulrich

EMPA, Switzerland

开发了Micro-floe-capillary online-coupled to plasma mass spectrometer的系统，已经在铝合金、锆基非晶、镁合金等研究上有文章，镁合金方面看晶界上的夹杂物对腐蚀的影响，溶液中Ca2+对镁合金溶解的影响（Spectrochimica Acta part B 66(2011)536-545）

 

On-line in vivo degradation monitoring system for biodegradable metal implants: system development and in vitro validation

Emma P. Córcoles

Universiti Teknologi Malaysia, Malaysia

利用半透膜包裹电化学Biosensor然后设想可以利用镁离子和Glycerol+ATP变成glycerol-3-phosphate等系列反应最后引起染料的颜色变化，目前只是设想还没有在动物上试过。

 

On an improved testing setup for assessing the corrosion behaviour of pure magnesium and its alloys in simulated body fluid

Joelle Hofstetter

ETH Zurich, Switzerland

样品放置用teflon专用的，液面上放置中空塑料球以防止蒸发，通入CO2并初步认为 in vitro(CO2-buffered)=in vivo

 

Influence of Dy on the bio-corrosion behaviour of binary Mg-Dy alloys in cell culture medium

Lei Yang

Helmholtz-Zentrum Geesthacht, Germany

Dy的溶解度和生物相容性比其他稀土要好。Mg-10Dy降解速度最慢。

 

Fretting behaviours of magnesium and its alloys for future orthopedic application

Liqun Ruan

Peking University, China

介绍了不同载荷下纯镁、镁钙合金和AZ91合金在空气和模拟体液中的磨损腐蚀

 

Degradable behaviour and blood compatibility of surface eroding poly(1,3-trimethylene carbonate) coated biomedical magnesium alloy

Juan Wang

Southwest Jiaotong University, China

（PTMC）聚三亚甲级碳酸酯降解产物中性、1200%延伸率，基体为MgZnMn合金

 

Discussion of degradation pathways of Mg and Mg- alloys - the role of hydrogen evolution and / or the creation Mg-hydride

Wolf-Dieter Mueller

Charité Unviersitaetsmedizin Berlin, Germany

在OCP测试时候会形成MgH2,讨论了其对降解的影响。
