Abstract:A new method for obtaining graded amorphous carbon using quenching of a graphite melt on
a diamond substrate is proposed. Using molecular dynamics modeling of liquid carbon quenching
on a cold diamond substrate, it is shown that the amorphous carbon obtained in the experiment
is a material with a strongly gradient structure and properties along the depth of the sample.
This is due to the quenching rate decrease with the distance from the substrate in the range
of 10^14-10^12 K/s. In this case, the density… Show more
