The growth kinetics of diamond on carbon composites was investigated. The m
icrostructure was examined using scanning electron microscopy and Raman spe
ctroscopy. Growth rates were determined at various deposition temperatures
and the activation energies were calculated. The activation energies range
from 34.7 to 55.6 kJmol(-1), depending not only on the deposition condition
but also the substrate used. (C) 2001 Elsevier Science B.V. All rights res
