The studies in Center for tribology and technical diagnostic under the guidance of dr. Kalin in cooperation with coworkers at Institute of Jožef Stefan are recently worldwide leading. Work was orientated on influence of surface charge and pH of aqueous solutions on formation and properties tribochemical layers on ceramic materials. Completely new findings relevant for boundary lubrication were found.

In this paper we present a new tester dedicated for evaluating the tribological performance of ceramic-based composites for brake applications that uses reduced-scale samples with conformal contacts. The results confirmed our assumptions about the very high temperatures that are generated at the ceramic contacts and the necessity for well-controlled contact conditions. In addition, these first results suggest there are some beneficial frictional properties with a new material combination using in-house-developed MMC pads and C/C-SiC discs.

The book, edited by J. Vižintin and M. Kalin with two other authors was written on the base on international conference Slotrib, Ljubljana. Since the conference attended some eminent scientists, we added to these authors several others and presented works on the whole international scene. The book treats recent state of various fields in which tribologists are interested in. The book was published by international publisher ASME Press, which publishes under patronage one of the biggest engeeniring organization with about 125.000 members, ASME. 600 copies are already sold.

The book Surface Modification and mechanisms: friction, stress, and reaction engineering, was published in the year 2004. It was written by international recognized scientists. To creation of this book prof. dr. Jože Vižintin was also invited. His chapter very carefully considers physico-chemical processes in lubrication regime. The author gave special attention to understanding of additives action, which is the clue for the successful application of oils in practice, contributing to scientific value of the book, but also to its application in industrial acquaitances. 70% of copies are sold.

(i) We have proved that some DLC coatings operate much better with lubricants if some other elements are added in their structure (ii) We first presented clear chemical evidence for reaction between undoped pure amorphous DLC coatings and additives when mineral oil was used and it was found that they form protective boundary lubrication films (iii) We also found that the use of unsuturated and polar base oils improves the properties of boundary lubrications for great extent, most probably due to adsorption mechanisms of polar molecules, similar to what is known for metal surfaces.
