Abstract
Nanocrystalline carbide/diamond-like carbon composite films and synthesis method near room temperature are described wherein combined magnetron sputtering and pulsed laser ablation produce plasma fluxes intersecting on a substrate surface to form metal carbide and diamond-like carbon composite films of about 10 to 50 nm carbide crystallites encapsulated in a sp.sup.3 bonded amorphous diamond-like carbon matrix having a hardness of about 32 GPa and high plasticity, high toughness in contact loading and low friction coefficient.
