Abstract

Nanocomposite coatings are attractive due to their unique mechanical, physical and multifunctional properties, which can address the limitations of conventional monolithic structures to achieve an excellent combination of strength, stiffness, toughness, and some other functional properties. In this study, a novel in-situ low temperature (below 500ºC) hybrid plasma technology combining active-screen plasma co-sputtering and PECVD has been developed to cost-effectively generate vertically aligned carbon nanotubes (VACNTs) films. A two-step approach has been employed to develop VACNTs reinforced composite coatings. A well-designed CNTs reinforced diamond-like carbon (DLC) composite coating can be formed using the PECVD. Besides, the Ag wires reinforced composite coatings have been deposited through a one-step approach using the advanced hybrid plasma technology combining ASP co-sputtering and plasma carburising in a plasma ambient of CH4 (1.5%) and H2 (98.5%). SEM, TEM, XRD, XPS have been applied to characterise the morphologies and microstructures of these novel composite coatings.
