Novel coatings combine protection with colour effects

27.03.2015

New coloured protective coatings offer corrosion and wear protection and could for instance also be used as a warning colour on surfaces which can get very hot.

New coloured protective coatings offer the same corrosion and wear protection as colourless coatings while their colouration opens new opportunities. Red could for instance be used as a warning colour on surfaces which can get very hot.

The new possibilities from combining protection and colour in such coatings will be demonstrated by INM – Leibniz Institute for New Materials at this year’s Hannover Fair from 13 to 17 April as an exhibitor at the leading Research & Technology trade fair (stand B46 in hall 2).

“Incorporating coloured pigments in nanocomposites make coatings possible which are not only protective but also deliver additional visual information via their colouration,” explains Peter William de Oliveira, head of the IZI - Innovation Center INM.

A protective coating for surfaces of ovens, chimneys or certain automotive parts could be coloured red for instance. So such parts would not only be protected from corrosion, wear and oxidation but at the same time also be distinctive to the consumer by virtue of their colour.

To create a full red shade without brown content, INM researchers are currently working on ceramic particles with red pigments free from iron oxide. Chemical compounds previously used were not very suitable for such applications.

“Organic compounds do make for very nice reds – but they are unsuitable for such protective coatings, since organics do not survive high temperatures,” explains the physicist de Oliveira, “Iron oxides do withstand high temperatures when used as colouring particles for reds, but do not give full reds.”

Black coloured coatings with a thickness of two to five micrometres can withstand temperatures up to 900 degrees Celsius, but also coatings with a reddish brown colour with resistance can endure up to 500 degrees Celsius. INM researchers are also developing protective coatings using blue and green pigments. Current developments at INM enable the use of these coloured glass-ceramic layers on metals and glasses. The pigments are incorporated in sol-gel nanocomposites and applied by dipping or spraying.

INM conducts research and development to create new materials – for today, tomorrow and beyond. Chemists, physicists, biologists, materials scientists and engineers team up to focus on these essential questions: Which material properties are new, how can they be investigated and how can they be tailored for industrial applications in the future? Four research thrusts determine the current developments at INM: New materials for energy application, new concepts for medical surfaces, new surface materials for tribological systems and nano safety and nano bio. Research at INM is performed in three fields: Nanocomposite Technology, Interface Materials, and Bio Interfaces.
INM – Leibniz Institute for New Materials, situated in Saarbrücken, is an internationally leading centre for materials research. It is an institute of the Leibniz Association and has about 210 employees.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
