The effect of thermal annealing on properties of carbon films deposited on
nickel electrodes by the electrodeposition method was studied. It has been
shown that annealing at a temperature of 300 degrees C results in the forma
tion of nanosize diamond clusters. With an increase in the annealing temper
ature, the size of diamond clusters diminishes. At an annealing temperature
of 900 degrees C, all of the carbon enters into reaction with nickel, thus
forming nickel carbide. (C) 2000 MAIK "Nauka/Interperiodica".
