Unexpected wear increase is observed on a steel surface that rubbed against diamond‐like carbon (DLC) coatings only when lubricated by phosphate‐based antiwear additives. Contradictory to the literature hypothesis of a competition between zinc dialkyldithiophosphate produced tribofilms and DLC‐induced carbon transfer, here a new wear mechanism based on carbon‐catalyzed tribochemical interactions supported by surface characterization is proposed.
