According to a report from Czech Republic Agency of Communications in Prague, the Czech HiLASE Laser Center recently announced that a research team at the center has discovered a method of using a laser to quickly and accurately establish a regular structure on a metal surface, which can be applied in aircraft manufacturing.
The technology was developed by the HiLASE team in collaboration with Italian counterparts. It is possible to create periodic structures with sub-micrometer dimensions or less than one-thousandth of a millimeter, which is crucial for the selected branch of research. Such structures are hardly noticeable to the human eye, so they can be part of the security protection factor. In the aviation industry, periodic microscopic and macroscopic structures are important. They can prevent the freezing of water on aircraft wings, but how to build such a structure on a large surface has always been a problem.
HiLASE experts have successfully used laser pulses to create conventional pre-selected structures on metal surfaces such as aluminum, titanium, copper, molybdenum, gold and steel. This effect may apply to a large number of elements and materials and may even apply to all metals. The new method is faster and more accurate than the technology used so far, greatly increasing the potential for use in practice.
The study was initiated by scientists from Modena, Italy. They tested their success with their own methods, but they were limited to selected materials and therefore sought help from HilASE. Experts expect that the new method will replace the costly and laborious methods applied so far, such as dusting, chemical and plasma burning, nanoimprinting and so on.
HiLASE is part of the Institute of Physics of the Czech Academy of Sciences. It was founded in 2014 and is dedicated to the development of a new generation of lasers, which costs 850 million kronor, 85% of which comes from EU funds.
