Researchers of Fraunhofer Institute for Manufacturing Engineering and Automation IPA in Stuttgart and Duisburg-Essen University have developed a process for producing electroplated layers with nano-capsules. Evenly distributed fluid-filled capsules are embedded into the electroplated layer deposited on materials like metals for protecting from corrosion. If the layer is damaged, the capsules release fluid and repair the scratch and thus rust protection is achieved. The researchers have produced the first copper, nickel and zinc coatings with the new capsules. Mechanical bearings are one example of possible applications.
