The properties of nanocomposite carbon-nickel-palladium (C-Ni-Pd) films deposited on Al2O3 substrate have been investigated and the results are presented in this work. C-Ni-Pd films were obtained by a 3 step process consisting of PVD/CVD/PVD methods. The structure and morphology of the obtained films were characterized by scanning electron microscopy and transmission electron microscopy techniques at various stages of film formation. Energy dispersive X-ray spectrometer was used for measuring the elements segregation in the obtained film. Transmission electron microscopy and scanning transmission electron microscopy observations have shown carbon nanotubes decorated with palladium nanoparticles in the final film. The average size of the palladium nanoparticles did not exceed 10 nm.
