In cooperation with the Swiss CERN, Sirris is evaluating the creation of cooling channels in silicon wafers by means of femtosecond (fs) laser ablation.

The application of nanotextures with ultra-short pulsed lasers remains interesting for many applications and LIPSS (laser induced periodic surface structures) is the most widely used technique. A newly developed module makes it possible to achieve more precise, higher-quality structures, even on large surfaces. This is particularly interesting for anti-icing surfaces, as applied in aviation or wind energy.

The build-up of ice on the wings and propellers of an aircraft, drone or wind turbine results in reduced lift or increased consumption. Ice formation may be actively and passively combated. It’s recently been shown that making the surface superhydrophobic in certain weather conditions can counteract this ice formation.

Thanks to the ongoing evolution of laser technology, the application possibilities are steadily expanding. This is no different with femtosecond laser technology.

Ultra-black is an interesting colour for many sectors, for aerospace, first of all, and for several reasons. It can be achieved with black coatings, however, there are some limitations to this methodology. That is why Sirris, together with ESA, is investigating laser texturing to achieve ultra-black, without any additional disadvantages or limitations.

What is profitable today will have been replaced by a better solution by tomorrow. You know better than anyone else the need for innovation to stay ahead of your competitor or partner. New technologies often lie at the root of these changes. Staying informed is therefore a must!

Industrial blades are used for many different processes. Their service life depends to a great extent on the application. A new COOCK project aims to offer a solution by studying the crucially important parameters of material, surface treatment and core treatment.

LED lighting is currently breaking through in various branches of the lighting industry. This type of lighting is powerful, economical and has limited dimensions. For a more efficient production, femtosecond laser technology can be used.

Friction between moving parts plays an important role in many applications. The lower the friction, the less energy is needed to move parts and the less wear and tear will occur. Research at Sirris has shown that applying small holes in sliding surfaces has a positive effect on friction behaviour.

What is the role of surface functionalities and, in particular, the role of textures, in the manufacturing industry in Belgium? That is the question we asked our member companies last summer with a view to rolling out a service on surface textures. The (concise) results are presented in this article.
