Many researchers nowadays concentrate on nanocrystalline metal-matrix composites, as well as on composites reinforced by nanoparticles, to find more suited materials to be used in aviation, nuclear power plants or as a hydrogen storage for fuel cells. The aim of this paper was to investigate the possibility of producing nanocrystalline nickel-based composite coatings reinforced by carbon nanotubes (Ni–CNT). The goal was to obtain well immersed carbon nanotubes fully dispersed in nanocrystalline nickel matrix by using standard electrochemical deposition equipment and modify the process by changing parameters like bath composition, additives, nanotubes content or stirring method. The effect of optimization of these parameters on composite’s microstructure, surface topography and nanohardness was investigated. Also, usefulness of different approach, so called “stirring electrode” was examined. Scanning electron microscopy, transmission electron microscopy with electron diffraction, X-ray diffraction and Raman spectroscopy were used to determine the microstructure of obtained coatings.
