  • Fraunhofer lighthouse project "futureAM" expected to speed up "additive manufacturing" by a factor ten / 2019

    Additive machines discover superalloys

    Press release (No. 6) - Fraunhofer IWS Dresden / 17.5.2019

    By means of laser powder build-up welding, components made of different materials can be integrally manufactured. Thus, specific materials can be placed exactly where their properties are required. This offers, for example, the prospect of lighter, better and cost-reduced blades for gas turbines.

    Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed innovative methods enabling more materials to be processed in additive manufacturing than ever before. For example, additive manufacturing systems could facilitate better future aircraft engines with lower fuel consumption. However, engineers must first improve the current industrial 3D printers in such a way that these machines can also process very strong and extremely heat-resistant alloys. Here, the Dresden researchers rely on their profound experience with laser powder buildup welding technologies and employ artificial intelligence (AI). They contribute their profound materials expertise to the Fraunhofer joint project "futureAM". The aim of the partners is to speed up additive manufacturing systems for metal components by a factor ten and also to manage superalloys.

  • Fraunhofer IWS is developing innovative solutions for current challenges of lithium metal anodes / 2019

    Key component for batteries of the future

    Press release (No. 5) - Fraunhofer IWS Dresden / 3.4.2019

    Lithium coating on copper foil created by IWS melt deposition: The process already permits producing prototype cells with lithium anode layers of 5 to 30 micrometers in thickness.

    Fraunhofer IWS scientists headed by Dr. Holger Althues have developed an innovative process for the cost-efficient production of thin lithium anodes made of molten lithium. In the BMBF-funded “MaLiBa” project, the Dresden Institute is working with the companies hpulcas and SGS as well as with scientists led by Prof. Dr. Jürgen Janek of the Justus Liebig University in Giessen to solve further crucial issues relating to this concept. The most important innovation consists in realizing an anode compound. This contains a few micrometers thick nickel foil with lithium film stabilized by means of protective layers.

    Together with the automotive industry, researchers at the Fraunhofer IWS have been working to develop processes for friction-reducing surfaces of engine components over the past few years. Now, carbon dioxide emissions can be reduced even further by enhancing surface technology. The Dresden Institute is researching in this direction with various partners in the joint project "Prometheus".

    Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a joining gun that creates a connection between metal and thermoplastic materials within seconds. This gun is of a modular design and can easily be integrated into the production process, for example by mounting on a robot arm in place of a spot welding gun. At the preview leading up to the Hanover Trade Fair on January 24, 2019 on the trade fair grounds in Hall 19, scientist Annett Klotzbach will be demonstrating the advantages of the joining gun.

  • Tribology: Design Rules for Extremely Low Coefficients of Friction / 2019

    Elucidating the Atomic Mechanism of Superlubricity

    Press release (No. 1) - Fraunhofer IWS Dresden / 11.1.2019

    Oleic acid (colored) forms chemical bonds with both ta-C surfaces (black). Movement causes the oleic acid to pull, a hydroxyl group splits off and superlubricity is formed.

    The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
