A large number of technologies and technical product properties are based on surface and border area phenomena. Here, coatings just a few micrometers or nanometers thick and lateral structures of similar dimensions are relevant to the property. These include for example electrical and optical properties, friction and wear, wettability, adsorption, adhesive properties, bondability and solderability, diffusion, oxidation, passivation, corrosion, electrodes/electrolyte border area properties as well as biostability and biocompatibility. The testing and modification of the properties is a focal point of the key working area of surface and border area technology at the NMI.
The conducted research projects and services are grouped in the areas of surface technology, microstructure analytics and tribology.
A particular speciality of the NMI is the use of these technologies for biotechnical and medical applications. |
When two solid bodies move against each other, friction, wear and material damage occurs. These can be reduced by lubrication. It is estimated that about half of the generated energy is used to overcome friction. About 1 % of the gross national product could be saved world-wide by optimising tribological systems. Lubrication is achieved by introducing moving molecules into the gap between the friction partners. The NMI uses border area methods to research how these moving molecules reduce friction, wear and material damage.
