Today's car enthusiasts have a diverse range of requirements: popular issues that concern them include safety in the vehicle, a good driving experience, a powerful engine and sophisticated technology.
If drivers want to make an impression with their vehicle, decorative elements such as coloured wheel rims, brake calipers, exhausts, footboards or bodywork and engine components are increasingly being added. In an ideal scenario, it is possible to combine decorative coatings with protection from corrosion and wear.
INM will be presenting such coatings at this year's IAA International Motor Show. It will present its results in cooperation with automotive.saarland in Hall 4.0 at Stand D27.
The coatings have glassy and glass-ceramic properties. They therefore reduce the level of corrosion and wear, susceptibility to scratching or tarnishing and other processes of oxidation on surfaces.
To complement these protective properties, depending on the choice of colour pigments, the INM production method can be used to produce the colours of red, black, green, white and blue for decorative purposes with stability at high temperatures.
These functional coatings are suitable for metallic substrates such as steel, aluminium or alloys or as a protective layer for glassy components.
"In addition to the properties which have been mentioned, our production method also opens up other possibilities," says Peter William de Oliveira, head of the Optical Materials program division. These include possible non-stick properties, a certain flexibility in the layer or also the possibility of electrical insulation as a result of the vitreousness.
The INM uses special silicates for the coatings. They are converted into a sol-gel nanocomposite in a single-step reaction. Depending on the colour pigment and the substrate, this means that surfaces can be hermetically sealed at from 200 to 800 degrees Celsius.
The thickness of these layers ranges from two to ten micrometres. Curved and flat surfaces can easily be covered with the coating in immersion chambers or spray booths.

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.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
