Abstract

In this study, friction behaviour of as-deposited and N⁺ ion-implanted nanocrystalline diamond films was investigated. In as-deposited film, the friction coefficient in ambient and humid condition was 0.8. Such a high value is explained by the formation of strong bonds across the sliding interfaces. In contrast, under similar test condition, friction coefficient of N⁺ ion-implanted film was ∼0.07. The significant decrease in friction coefficient is ascribed to the formation of covalent CN_x phase which limits the formation of strong bonds in sliding interfaces.
