Szukana fraza: [Abstract = "Modern automotive designs are needed to increase mechanical and thermal loads that have longer lifespans and are lighter. The power transmissions and motors often use low\-friction hard coatings to prevent wear and reduce friction. The Cr\-doped graphite\-like carbon method is employed for evaluating coating friction and responses to chromium\-doped graphite\-like carbon \(Cr\-GLC\) under lubrication. Cr\-GLC coatings and chromium\-doped diamond\-like carbon \(Cr\-DLC\) coatings are arranged using physical vapor deposition \(PVD\) and plasma\-enhanced chemical vapor deposition \(PECVD\), respectively."]
