The results we have presented represent completely new findings on the level of physical adsorption mechanisms and lubrication in the elastic-hydrodynamic (EHD) regime. We discovered that friction significantly depends on the wetting properties of surfaces. Therefore, in the full EHD lubrication regime, where there are no contacts between surfaces, friction can be affected only by altering the physicochemical properties of surfaces, without changing the lubricant.

COBISS.SI-ID: 10890267Since 2006 dr. Kalin works as associate editor one of the main renowned SCI journals in the field of tribology, the Journal of Tribology. Currently he is working his second three-year mandate. For journal he independently defines reviewers, asses their work and lead procedure of articles evaluation, and finally makes independent decisions on publication of articles. With that he indirectly actively directs and evaluates research in the world, and helps to the program group at its visibility and quality.

COBISS.SI-ID: 7267077We discovered that in DLC contact boundary layers are formed only with the use of PAO base oil or pure alkanes. These boundary layers influence the tribological properties of the contact. Since they are highly chemically pure, alkanes can absorb on the DLC surface only with the weak van der Waals forces. This clearly shows that due to the functioning of physical adsorption mechanism boundary lubrication is possible on DLC surfaces without the addition of polar groups or additives.

COBISS.SI-ID: 11148315We presented a new concept for lubrication design, such that has not yet been made for macro-engineering contacts. Namely, when considering the physical properties of materials it is necessary not only to take into account the solid-solid contacts, but also the solid-liquid contacts, since due to the slip of the lubricant on the surface they can have a very large influence on friction.
