By repetitively pulsed laser treatment with a frequency of 500 Hz was metal/semiconductor nanocomposite on a basis of zinc oxide nanowires created. An analysis of results made it possible to find that with described laser-induced vibroexcitation of samples, vibration speed increases for frequencies multiple to frequency of the initial oscillation, and when frequency is increasing the amplitude is decreasing. Samples heating particularities in consequence of laser irradiation were determined. Analysis of X-ray diffraction images showed that the zinc oxide creation on the porous copper-zinc alloy substrate occurs as a result thermal oxidation by the repetitively pulsed laser treatment. It is shown that intensification condition of mass transfer in a solid state of a metal material is a local non-stationary deformation that is produced by a highly-powered outer action. Using of synergies of thermal action and vibrations in a sound frequency range caused by laser irradiation, provides opportunity of a new approach realization for the structures creation of composite nanomaterials on a basis of zinc oxide in metal/semiconductor Cu/ZnO nanocomposite.
