Abstract
A method for fabricating a carbon-based composite material includes: bearing a carbon-based composite material layer containing an amorphous carbon matrix and a plurality of equi-axed ultrananocrystalline diamond grains dispersed in the amorphous carbon matrix on a susceptor and applying a plasma treatment on the carbon-based composite material layer in a plasma environment containing a Cspecies and a CN species. The susceptor is provided with a negative bias voltage, and is bombarded by the plasma species to be naturally heated to a working temperature less than 500° C. The Cspecies and CN species are attracted by the negative bias voltage to the carbon-based composite material layer to make the carbon-based composite material layer generate a phase transformation, so as to facilitate growth of each of the adjacent equi-axed ultrananocrystalline diamond into a nano needle-like diamond grain wrapped by a nano graphite phase.
