microCT test system with nanofocus X-ray source including software package for 3D-reconstruction

斯特拉尔松应用科学大学附属于机械工程学院材料与制造技术部的生物材料与轻质建筑工作组正在申请一种高分辨率X射线微CT，用于样品或部件结构的体积三维重建。在斯特拉尔松德应用科学大学，生物材料与轻质建筑研究领域嵌入了两个主要研究领域：(1)具有能力领域的生物材料的卫生技术；(2)具有能力领域的技术系统和能源效率；(2)轻量级建筑和材料科学，因此受到应用科学大学的特别关注。生物材料领域的焦点是作为金属生物材料的镁合金。该工作组正在对可生物降解镁合金及其腐蚀行为进行深入研究，重点研究腐蚀形态。这种所谓的生物镁的可能应用是骨螺丝、伤口闭合夹、骨钉、钉、支架和电线。在这里，与其应用相适应的均匀腐蚀速率是必不可少的。First产品已经在市场上出售了。机械工程学院目前正计划设立一个保健技术专业领域；微型计算机断层扫描完全符合加强这一领域的意图。多年来，轻量化建设一直是学校的兴趣所在，汽车工程是一个既定的专业。工作组的另一个重点是在多材料设计的背景下将纤维复合材料连接到高强度变形铝合金，以及在车辆和飞机结构中连接相似和不同的变形铝合金。该工作组还在用于添加剂制造的生物兼容材料的开发和化学适应方面经验丰富。重点是用于光聚合的丙烯酸酯的发展，特别是立体光刻。所要求的MicroCT旨在提供关于镁和铝基金属轻质合金以及纤维复合塑料和聚合物基材料的内部结构的信息。这既适用于初始状态，也适用于机械(静态、循环)和腐蚀测试的结果。这使得材料的状态/质量(微结构、制造缺陷)与所产生的性能相关联，并为材料和工艺优化提供了最佳基础。斯特拉尔松应用科学大学还没有X射线微CT设备。斯特拉尔松德附近地区没有这样的设备，达到所要求的性能级别，或者两者都没有。除了已有的合作外，新系统还提供了扩展新研究合作的可能性。

The working group Biomaterials & Lightweight Construction at the University of Applied Sciences Stralsund, affiliated in the School of Mechanical Engineering - in the Materials and Manufacturing Technology division, is applying for a high-resolution X-ray microCT for the volumetric 3D reconstruction of samples or component structures. The research area Biomaterials & Lightweight Construction is embedded in two main research areas at the University of Applied Sciences Stralsund: (1) health technologies with the competence field biomaterials and (2) technical systems and energy efficiency with the competence areas lightweight construction and material science and is therefore in the special interest of the University of Applied Sciences. The focus within the field of biomaterials is on magnesium alloys as metallic biomaterial. The working group is intensively researching on biodegradable magnesium alloys, their corrosion behavior with a focus on corrosion morphology. Possible applications of this so-called biomagnesium are bone screws, clips for wound closure, bone nails, pins, stents and wires. Here a uniform corrosion rate adapted to its application is essential. First products are already available on the market. The School of Mechanical Engineering is currently planning to establish an area of specialization in health technologies; a microCT fits perfectly to the intention to strengthen this area. Lightweight construction has been in the interest of the school for many years, automotive engineering is an established specialization. Another focus of the working group is joining of fiber composite materials to high-strength wrought aluminum alloys in the context of multi-material designs as well as the joining of similar and dissimilar wrought aluminum alloys in vehicle and aircraft constructions. The working group is also experienced in the development and chemical adaptation of biocompatible materials for additive manufacturing. The focus is on the development of acrylates for photopolymerization, especially stereolithography. The requested microCT is intended to give information on the internal structure of metallic lightweight alloys based on magnesium and aluminum, as well as of fiber composite plastics and polymer-based materials. This applies both in the initial state and as a result of mechanical (static, cyclical) and corrosive testing. This enables a correlation of the state/quality of the material (microstructure, manufacturing defects) with the resulting properties and allows the best basis for material and process optimization. The University of Applied Sciences Stralsund does not have an X-ray microCT facility yet. The near region of Stralsund has not got such a devices of the requested performance class or either. In addition to the given collaborations, the new system offers the possibility to expand new research collaborations.
