||
8月29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-2Ag、Mg-4Ag、Mg-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Alginate和Poly-l-lysine在AZ31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。
8月29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0.009atm的CO2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次
