Abstract:
The present invention relates to a component part comprising at least two components movable with respect to one another, between the surfaces of which is provided a film formed by a lubricant oil composition, the surface of at least one of the movable components being formed at least partly by a diamond-like-carbon layer (DLC layer) and the lubricant oil composition comprising at least one polymer comprising repeat units derived from amine derivatives of at least one polar ethylenically unsaturated monomer.
