Corrosion and Wear Protection: Economical, Environmentally Friendly and Extremely Fast

Press Release / 31.5.2017

Components are protected against corrosion and wear through hard chrome plating, thermal spraying, laser material deposition or other deposition welding techniques. However, there are downsides to these processes – for example, as of September 2017, chromium(VI) coatings will require authorization. Researchers from the Fraunhofer Institute for Laser Technology ILT in Aachen as well as the RWTH Aachen University have now developed an ultra-high-speed laser material deposition process, known by its German acronym EHLA, to eliminate these drawbacks. On May 30, 2017, the research team was awarded the Joseph von Fraunhofer Prize for this work.
