Study on Comparative Experiments of Performance of Conventional and Nanocrystalline Diamond Film

Abstract:

Article Preview

Nanocrystalline diamond film with smooth surface and uniform grains was deposited successfully on Co-cemented carbide using the bias-enhanced hot filament chemical vapor deposition (HFCVD). The surface morphology and chemical quality of film were estimated by scanning electron microscopy (SEM), atomic force microscopy (AFM) and Raman spectroscopy. Comparative experiments of tribological and wear performances of conventional and nanocrystalline diamond films were carried out by pin-on-disc tester. The research results show that nanocrystalline diamond film with good tribological performance and high quality can be deposited by regulating the deposition parameters on Co-cemented carbide. The film not only has high adhesive strength but also has smooth surface, low surface roughness, low friction coefficient. The work done in this paper provide the wide application of diamond on complex shape tools, drawing dies and other wear resistant device with experimental reference.
