Surface coating

Friction reduction and wear protection

Functional coating on motor components.

Favourable friction behaviour and high wear resistance are surface characteristics that play an ever-increasing role for improving performance and in the development of new products in many areas of mechanical engineering and vehicle construction. Simultaneously optimising additional properties of multifunctional film systems constitutes a special challenge which is overcome with plasma technology processes by the Centre for Tribological Coatings at Fraunhofer IST.

Electrical functional films are key components in numerous products. The Fraunhofer Institute for Surface Engineering and Thin Films IST develops such films on a customer-oriented basis for new film materials and film material combinations with defined electrical characteristics as well as the corresponding coating processes.

Thin film sensors offer a variety of possibilities for the integration of sensor functions such as force, pressure, elongation and temperature measurement in existing components. Smart tools with extended functions enable highly accurate measurements of stresses in a wide variety of industrial application fields.

Photocatalysis

Simulation of a photocatalytically active surface.

Photocatalytically active coatings are used to give self-cleaning properties to surfaces, clean air and water, or kill bacteria, algae and fungi. Organic contaminants are degraded to H2O and CO2 by irradiation with light of a suitable wavelength, usually UV light. In principle, the photocatalysis dispenses with additional chemical substances and is therefore one of the most environmentally friendly and sustainable technologies.
