Airbus Defence and Space has built the Electromagnetic Levitator (EML) facility which was developed under parallel contracts of the European Space Agency ESA and the DLR Space Administration.

EML is a containerless processing furnace for materials research in the European Columbus lab, set to uncover a deeper understanding of advanced alloy and semiconductor materials and their molten state properties for the optimisation of industrial scale casting as well as for basic research. The EML together with the first batch of samples is part of the cargo complement scheduled to be transported to the International Space Station (ISS) in June by the European resupply spacecraft ATV-5 (Automated Transfer Vehicle).

At least until 2020 the unique test facility will process various metal and semiconductor samples at temperatures of up to 2,000 degrees Celsius in a series of experiments, using the principle of electromagnetic levitation and inductive heating.

Several teams of materials scientists and industrial researchers have the objective to acquire high precision data of temperature-dependent thermophysical properties of molten advanced materials, which play a key role in complex casting and solidification processes for these materials when they are used for parts manufacturing on an industrial scale.

Performing levitation under microgravity conditions requires only small levitation forces, and deformation of the samples will be avoided which falsifies the measurements based on in-situ optical principles.

It is almost impossible to imagine modern life without products made from high-tech materials. They are used in industrial goods such as jet turbine blades and clean engines for cars. They include supermetals used to make electronic components and high-performance magnets, as well as medical devices such as artificial joints and prosthetics. They are even found in fine metal powders used as catalysts in chemical reactions.

Understanding more about materials properties in liquid state for casting models and solidification parameters for these advanced materials is essential both for monitoring the parts' production process and secure a high quality of the manufactured products.

To this end, a continuous series of experiments are due to be performed by the new EML facility, which will be accommodated in the European Drawer Rack in the Columbus Laboratory on the ISS. Weighing in total approximately 360 kilograms, the EML facility consists of four modules, the most important of which is the Experiment Module (EXM).

The samples, which are stored in special containers made from ceramic and rhenium, are fed into the process chamber in a similar arrangement to the magazine of a revolver. This magazine contains 18 spherical metal samples for the experiments, including various aluminium, copper and nickel alloys.

For processing one sample at a time is positioned using electromagnetic levitation and then molten by inductive heating in an electromagnetic field generated by a coil system. Numerous parameters can then be measured simultaneously on the levitated metal droplet. Containerless non-contact methods will be used for all the experiments in order to avoid any interference on the measurements compared to the necessary use of a crucible on ground.

Operation of the Electromagnetic Levitator will be controlled and monitored by the German Aerospace Centre's User Control Centre (MUSC) in Cologne. The scientists in charge of the experiments can carry out real-time, direct tracking of each and every detail of the melt cycles from this control centre thanks to a digital video observation camera, a high-speed data camera capable of capturing up to 30,000 images per second, and a pyrometer.

Before flight the individual sample materials have been thoroughly characterized before on parabolic flights with the Tempus facility provided by DLR. The ISS samples can even be returned to Earth at a later point in time to enable the researchers to perform further testing.

The Electromagnetic Levitator facility was developed and built by teams of Airbus Defence and Space Space Systems as industrial prime contractor. With over 25 years of experience in this field, Friedrichshafen experts built a number of flight units as part of the Tempus project, for parabolic flights (20 second experiment duration), sounding rockets (6 minutes) and for three Spacelab missions on board the U.S. Space Shuttle (1-2 weeks' mission duration) in the 1990s. Nowadays the ISS laboratories provide continuous access to microgravity conditions.

Silver gone astray
Lausanne, Switzerland (SPX) Feb 26, 2014
It has long been known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Yet to this day, there is a lack of detailed knowledge about the doses required to trigger a response and how the organisms deal with this kind of stress. To learn more about the cellular processes that occur in the cells, scientists from the Aquatic Research Institute, Eawag, subjec ... read more
