【 摘 要 】

Nanocrystalline diamond (NCD) particles are incorporated into diamond-like carbon (DLC) films in order to prevent NCD-DLC electrochemical corrosion. In the current paper, tribological behavior of NCD-DLC films under aggressive solutions is discussed. DLC and NCD-DLC coated steel disks and coated and uncoated steel ball were used under rotational sliding conditions. Raman scattering spectroscopy analyzed the film's atomic arrangements and graphitization level before and after tribocorrosion tests. The NCD-DLC films confirmed to be effective in the corrosion wear resistance under corrosive environments. The results pointed that NCD-DLC films are promising corrosion protective coating in aggressive solutions for many applications. (C) 2011 Elsevier B.V. All rights reserved.
