829日上午

Keynote 1: Impurities in the production and processing of magnesium alloys

Norbert Hort

Helmholtz-Zentrum Geesthacht, Germany

比较传统的一个报告,甚至可以适合所有的镁合金会议的对镁合金制造中的杂质控制。

 

 

R & D of capillary tube and stent of AZ31 Mg alloy used in vascular intervening fields

Zhentao Yu

Northwest Institute for Nonferrous Metal Research, China

介绍了西北院在AZ31镁合金毛细管的制造方法研究。

 

Extrusion of ultra-Fine grain size tubes for biodegradable stent application

Qiang Ge

Politecnico di Milano, Italy

采用ECAP制造超细晶镁合金,然后制造毛细管,用于血管支架。打算下一步做纯镁的。

 

Development of biodegradable bulk metallic glasses with elements of Mg, Ca, Zn and Sr

Yufeng Zheng

Peking University, China

介绍了可降解镁基、钙基、锌基和锶基非晶合金。

 

Magnesium silver alloys as multifunctional biodegradable biomaterials

Regine Willumeit

Helmholtz-Zentrum Geesthacht, Germany

做了Mg-2AgMg-4AgMg-6Ag合金,研究了降解和细胞毒性及抗菌性。

 

 

Friction stir processing of magnesium–nanoapatite composites for rapid biomineralization with controlled degradation

Ratna Sunil Buradagunta

Indian Institute of Technology Madras, India

利用搅拌摩擦焊在镁的熔池中加入纳米羟基磷灰石,很有趣的尝试,只是无法制备大厚度三维均匀的样品

 

Layer by layer development of natural polymer derived bioactive coatings on magnesium alloys

Prashant Kumta

University of Pittsburgh, USA

做了多层的天然高分子涂层AlginatePoly-l-lysineAZ31合金表面。

 

Cold-drawn bioabsorbable ferrous and ferrous composite wires: an evaluation of mechanical strength and fatigue durability

Jeremy Schaffer

Fort Wayne Metals, USA

该公司制备了75%90%99%冷变形的纯铁丝,0.1mm,另外做了芯部是镁外壳是铁的丝,应该可以去购买。

 

Novel processing of iron-manganese biometallic alloy by 3D printing

Da-Tren Chou

University of Pittsburgh, USA

利用铁粉和锰粉在Exone三维打印机上打印成骨头状样品,然后烧结处理,研究其生物相容性。

 

Co-deposition of iron and cobalt using electrolyte-adjusted electroforming method for cardiovascular stent application

Agung Purnama

 

Laval University, Canada

 

利用电沉积制备了Fe-Co合金膜,希望用于血管支架。

 

829日下午

PEO coatings of magnesium W4 alloy under in-vivo-in-vitro conditions

Amir Eliezer Sami Shamoon College of Engineering, Israel

降解速度可以降低90%,在羊上做了动物实验

Dynacast Deutschland GmbH&Co. KG, Germany

 

Biomimetic coating of magnesium alloy for enhanced corrosion resistance

Charles Sfeir University of Pittsburgh, USA

Peptide 仿生涂层

 

Optimization and degradation simulation of magnesium alloy stent: experimental verification

Dario Gastaldi  Politecnico di Milano, Italy

发展了唯象降解模型用于支架的有限元分析。

把支架撑开浸泡到D-Hank溶液看其Strut的断点,与有限元分析到的应力分布对应。

下一步将在降解模型中增加考虑降解产物层,偶极腐蚀和流动腐蚀。

 

Corrosion behaviour of Zr61Ti2Cu25Al12 amorphous alloy in artificial saliva and fluoride effect biological environment

Ling Ling Shi Chinese Academy of Sciences, China

介绍了Zr61Ti2Cu25Al12在模拟唾液中的腐蚀和表面的XPS结果。

 

Characterisation of the corrosion behaviour of the HZG Mg ingot produced for biodegradable medical applications by permanent mould direct chill casting

Andrej Atrens

The University of Queensland, Australia

高纯镁Fe的含量应该小于5ppm

镁降解应该用尽可能多的各种独立的方法。

 

Evaluation of coatings for Mg alloys for biomedical applications

Anna Da Forno

Politecnico Milano, Italy

利用0.009atmCO2可以维持溶液的Ph值。

OSi可以作为一个有希望的涂层。

 

Microstructural investigation on extruded Mg10Gd after exposure to fatigue and corrosion

Petra Maier

University of Applied Sciences Stralsund, Germany

120MPa循环,空气中2百万次,腐蚀疲劳寿命600,000
