Our coatings are used for corrosion and wear protection, optimization of biomaterials and polymers, and production of optical and decorative coatings. We are experts in PVD coating, sol-gel and electroplated coatings.

The spectrum of our coatings includes:

  • Metallic coatings by PVD or electroplating

    Aluminum, titanium, chromium, nickel, iron, cobalt, molybdenum, copper, zinc, silver, tantalum, rhenium, gold, rhodium, indium, tin or semi-metals such as silicon

  • Nitride or oxide layers by PVD and sol-gel

    e.g.: Silicon dioxide (SiO2), aluminum oxide (Al2O3), aluminum nitride (AlN), titanium dioxide (TiO2), titanium nitride (TiN), indium tin oxide(ITO)

  • Halide layers by PVD and sol-gel

    e.g.: Magnesium fluoride (MgF2), Calcium fluoride (CaF2)

Together with our customers, we develop coatings that are tailored to their individual needs. We can coat all common substrates such as metals, glasses and ceramics as well as plastics. Thanks to our many years of expertise, we know exactly which substrate pre-treatments and deposition parameters are applicable for the respective workpieces in order to obtain high-quality coatings with excellent adhesion.


LiMedion - Your partner for coatings and surface analysis




Our offer for surface analysis, material analysis and material analysis includes the determination of chemical composition, structure determination of organic compounds, microscopic investigations as well as the determination of material properties. The following methods/instruments are available for this purpose:

  • X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES).

  • FT-infrared spectroscopy (FT-IR), UV-VIS spectroscopy

  • Scanning electron microscopy (SEM) and light microscopy

  • Atomic Absorption Spectrometry (AAS)

  • Adhesion and coating thickness measurements

  • Hardness measurements and tensile tests to determine yield strength, breaking strength and elongation at break

  • Corrosion and electrochemical measurements
