In order to widely apply the diamond-like carbon (DLC) films to sliding elements, it is an urgent matter to elucidate the interaction with lubricant additives. This paper reviews the effects of lubricant additives on the tribological properties of DLC films under boundary lubrication regime according to recent researches. Friction modifiers (FMs) and anti-wear additives (AW) have different influences on the tribological performance of DLC films compared with metals. The design concept of DLC films based on “surface architecture” is introduced to develop DLC films tailored to conventional lubricant additives. However, the additional research is still needed to develop new lubricant additives tailored to DLC films for achieving a desired tribological performance and meeting environmental demands by revealing the tribochemical pathway of additives on DLC surfaces.
