Beschreibung
Zusammenfassung:	The invention relates to a component comprising at least two elements, which can be moved relative to one another and between the surfaces of which a film formed by a lubricating oil composition is provided, wherein at least a portion of the surface of at least one of the movable elements is formed by a diamond-like carbon layer (DLC layer) and the lubricating oil composition contains at least one polymer that comprises repeating units derived from amine derivatives of at least one polar ethylenically unsaturated monomer.
