Researchers develop laser-treated aluminium surface that is self-cleaning [Full subscriber]

Researchers at the Technische Universität Dresden and the Fraunhofer Institute for Material and Beam Technology IWS have developed a self-cleaning metallic surface. They have researched for several years on developing functionalised surfaces through laser treatment. They treated an aluminium plate with a laser process which produced a surface that was not only water and ice repellent, but also remove dirt particles solely by rolling water drops – completely without chemical cleaning agents or additional effort. The researchers focussed on aluminium largely because it is extensively “is used in many industrial branches – either in the automotive sector, aircraft construction or…
