【 摘 要 】

Multilayer fullerene-like hydrogenated carbon (FL-C:H) films were synthesized by using the chemical vapourdeposition technique with a different flow rate of methane. The typical fullerene-like structure of as-prepared films wasinvestigated by using transmission electron microscopy and Raman spectra. The prepared multilayered FL-C:H films showeda high elastic recovery ($\sim$90%), ultra-low friction coefficient ($\sim$0.019) and low wear rate ($\sim 3.0 \times 10^{−9}$ mm$^3$ Nm$^{−1}$) in humid air.
