Tribology: Design Rules for Extremely Low Coefficients of Friction

Elucidating the Atomic Mechanism of Superlubricity

Press release (No. 1) - Fraunhofer IWS Dresden / 11.1.2019

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
