Invited lecture discusses development of green lubrication based on several novel concepts, several of these based on own-derived results, heading in different directions: optimising chemical-based additives using low-SAPS concept, development of new additives based on ionic liquids, use of physical-chemical concepts of surface nano-engineering with wetting and surface energy modification, physical-based modifications through viscosity optimisation, molecules chain lengths and cohesive energies, use of nanoparticles as new additives for inert surfaces, topography modification using texturing, use of water-based lubrication, reduction of lubricant quantity by ensuring efficient boundary lubrication.

COBISS.SI-ID: 12559643The present invention refers to a lubricant additive, which is intended for lubricating of at least two steel machine parts, which are engaged with each other by means of sliding or rolling relative to each other, and moreover also to a lubricant containing such additive. A chemical structure of such additive is based on a linear molecule of alkane with preferably 10 to 20 carbon atoms, in which all hydrogen atoms, or all hydrogen atoms except of the terminal one, which is bound to the terminal carbon atom, are substituted with a fluorine atom or with such functional group on the basis of fluorine, which leads to oleophobicity of such substituted molecule, and wherein simultaneously at least one polar functional group is bound to at least one terminal carbon atom in order to assure adhesiveness of the additive towards the iron oxides on the surface of each lubricated machine part by simultaneously enabling sliding along the surface of the said machine part.

COBISS.SI-ID: 12214555In order to reduce losses in a piston machine due to resistance of the lubricant against displacing the piston (1) furnished with at least piston ring (3, 3',3'') along the cylinder (2), and consequently to improve efficiency of operation of such machine, the invention proposes a piston ring (3, 3',3''), which is furnished with a DLC-coating (31) on its peripheral surface (30), wherein said DLC-coating (31) contains 2 – 20 %, in particular 2 – 25 % of fluorine with respect to the total weight of the DLC-coating (31). The invention also relates to a piston (1), which is furnished with such piston ring (3, 3',3''), as well as to a piston machine comprising at least one piston (1) furnished with at least one piston ring (3, 3',3'') furnished with such DLC-coating (31) containing 2 – 20 %, in particular 2 – 25 % of fluorine with respect to the total weight of the DLC-coating (31), where the piston machine is either a driving machine like internal combustion engine, or a driven machine, like pump or compressor.

COBISS.SI-ID: 12491291Dr. Kalin was elected a Fellow of the STLE international tribologists association (2012) for his outstanding personal achievements and long term contribution in the field of tribology and lubrication engineering. A Fellow member of the STLE is recognized for the outstanding personal achievements in the field of education, management, research or technological development in the field of tribology and lubrication engineering. Each year, the STLE only elects 4-5 Fellow members worldwide. Since 1973 about 150 Fellow members received this award within the STLE, which is the only world tribology association with about 5000 members. Dr. Kalin is the youngest ever recipient of this award.
E.02 International awards
In 2012, dr. Kalin was elected as Editor in chief of Lubrication Science (Wiley), which is the only journal specialised in lubrication having SCI impact factor. After 20 years, he succeeded in this position prof. H. Spikes (Imperial College London), one of the most respected tribologists world-wide. With this, dr. Kalin became one of just few most respected journals in the field of tribology, suggesting his well-established reputation and importance of his work.
