  • Environmentally friendly: IWS Dresden ceramic coatings can reduce engine exhaust gases / 2019

    Heat shields for economical aircrafts

    Press release (No. 11) - Fraunhofer IWS Dresden / 17.9.2019

    Turbine blade with a thin ceramic coating of yttrium-stabilized zirconium oxide (YSZ): such a thermal barrier coating allows a higher operating temperature in the turbine, which improves the fuel yield.

    To make aircrafts more economical, environmentally friendly and robust, Fraunhofer engineers from Dresden have developed a new ceramic heat shield technology. In this process, a powder of yttrium-stabilized zirconium oxide (YSZ) is added to water to form a suspension. Quickly and cost-effectively this liquid powder mixture can be sprayed onto turbine blades or other aircraft parts. Such and similar thermal barrier coatings (TBCs) facilitate aircraft engines, which consume less fuel and do not contaminate the atmosphere as much.

  • “CleanRemote” protects work environment against hazardous micro dust / 2019

    Clean lungs thanks to laser process exhaustion

    Press release (No. 9) - Fraunhofer IWS Dresden / 18.6.2019

    The Multi Remote System (MuReA) by Fraunhofer IWS welds, cuts and structures components on a large scale and productively with high-power lasers. The resulting particles and emissions are safely extracted. CO2 snow blasting automatically cleans the machined surfaces directly after the laser process.

    In sectors such as the automotive industry, components can be processed at extremely high speed using the laser remote process. However, this can result in harmful emissions which may cause lung damage. Scientists from the Dresden Fraunhofer Institute for Material and Beam Technology IWS have studied the issue as part of the IGF research project “CleanRemote”. They reduce particles and gases in the air by means of a suction device.

  • "remoweld®FLEX" technology by Fraunhofer IWS makes nonweldable materials weldable / 2019

    Waterproof thanks to rapid lasers

    Press release (No. 7) - Fraunhofer IWS Dresden / 27.5.2019

    The Fraunhofer IWS technology known as "remoweld®FLEX" is suitable for particularly demanding processes, especially for components to be sealed media-tight against water and other undesirable environmental influences.

    Fraunhofer engineers from Dresden have developed a new laser welding process employing a fast oscillating laser beam. This technology, known as "remoweld®FLEX", is suitable for particularly demanding processes – especially for components to be sealed media-tight against water and other undesirable environmental influences. These include housings for electrical and electronic components, heat exchangers and coolings, which have previously been regarded as hardly weldable and often consist of die-cast aluminum. The Fraunhofer Institute for Material and Beam Technology IWS and Maschinenfabrik Arnold from Ravensburg were both involved in the research development.

  • 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.
