Effect of thermal annealing on spectral properties of electrodeposited carbon films

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°C results in the formation of nanosize diamond clusters. With an increase in the annealing temperature, the size of diamond clusters diminishes. At an annealing temperature of 900°C, all of the carbon enters into reaction with nickel, thus forming nickel carbide.
