The effect of thermally evaporated metallic NiCr dots on the adhesion, electrical, optical and the mechanical properties of RF‐PECVD grown diamond‐like carbon (DLC) thin films was investigated. The DLC films deposited over NiCr dots containing substrates exhibited a strong adhesion to the substrate. The observed drastic increase in magnitude of the current and the decrease of optical band gap due to presence of NiCr dots revealed a considerable improvement in their electrical and optical properties, respectively. Further, load versus displacement curves were employed to estimate the hardness (H), elastic modulus (E), plastic resistance parameter (H/E) and elastic recovery (ER). The values of H and E in NiCr dots containing DLC films were found to be comparatively less than that of DLC films. Overall, NiCr metal dots improved adhesion, optical and electrical properties of DLC films with a little deterioration in their mechanical properties (e.g. H, E, ER and H/E).
