The investigation was performed with steel/steel and DLC/DLC contacts, at 25 °C and 100 °C, in all lubrication regimes and by considering the running-in effect. Under all the investigated conditions the graphene platelets provided the lowest friction in the ML and BL regimes. This is the result of forming graphene-based tribofilms which, unlike for the other tested lubricants, is relatively insensitive to temperature, tribochemical activation and the conditions before or after the running-in. By combined the use of graphene platelets and conventional additives some interactions in their tribological behaviour were also observed.</dc:description><dc:date>2023</dc:date><dc:date>2023-01-11 09:37:40</dc:date><dc:type>Članek v reviji</dc:type><dc:identifier>143748</dc:identifier><dc:language>sl</dc:language></rdf:Description></rdf:RDF>
