Nanostructured coating based on the amorphous carbon matrix and silver nanocrystallites (nanoclusters) was obtained by pulsed vacuum-arc deposition method. It is found that instantaneous coating formation rate influences the size and amount of silver nanoclusters. The effect of the local inhomogeneous density distribution of silver nanoclusters and their coalescence at the initial stage of the coating formation was observed. Features of a separate silver nanocrystallite crystal structure were investigated using a high-resolution transmission electron microscopy. Electron energy loss spectra in the region of the amorphous carbon matrix and silver nanocrystallites location region, as well as the Raman spectra were obtained. Some promising applications of nanostructured carbon coating doped with silver have been proposed.
