“…Decades of research have focused on the search for diamond-like materials for practical applications. High pressure serves as a clean and powerful tuning parameter which has been used to investigate a number of carbon allotropes including graphite [5][6][7][8][9], C 60 and its derivatives [10][11][12], and carbon nanotubes [13][14][15]. Attractive physical/chemical/mechanical properties have been identified in these materials under compression.…”

Amorphous Diamond: A High-Pressure Superhard Carbon Allotrope

et al. 2011

Compressing glassy carbon above 40 GPa, we have observed a new carbon allotrope with a fully sp 3 -bonded amorphous structure and diamond-like strength. Synchrotron x-ray Raman spectroscopy revealed a continuous pressure-induced sp 2 -to-sp 3 bonding change, while x-ray diffraction confirmed the perseverance of non-crystallinity. The transition was reversible upon releasing pressure. Used as an indenter, the glassy carbon ball demonstrated exceptional strength by reaching 130 GPa with a confining pressure of 60 GPa. Such an extremely large stress difference of >70 GPa has never been observed in any material besides diamond, indicating the high hardness of this high-pressure carbon allotrope.

Tribological properties of nanocrystalline diamond films deposited by hot filament chemical vapor deposition

et al. 2012

View full text Add to dashboard Cite

The dependence of the structural and morphological properties of nanocrystalline diamond films grown by hot filament chemical vapor deposition on the substrate temperature was studied. Friction coefficients of these films were measured and found to vary from high to ultra low, depending on the chemical nature of the films i.e., sp2 and sp3 phase fractions. For all films, the friction coefficient was found to decrease with increase in sp2/sp3 phase fraction. The wear rate follows the trend of the friction coefficient and was likewise found to depend on the structural and morphological properties of the films. For all the films, the friction coefficient is found to decrease with normal load which is ascribed to sliding induced surface amorphization/graphitization
