Abstract: Disperse composite materials consisting of quasi-crystalline Al–Cu–Fe particles covered by nickel nanolayers have been obtained using a dusty plasma trap coating technology. These powders were processed into macrocomposites by cold pressing with subsequent sintering in hydrogen. The macrocomposites were studied by the electron microscopy, electron-probe microanalysis, and X-ray diffraction techniques. It is established that sintering at $\sim$750$^\circ$C yields a high-strength macrocomposite that is not fractured under tribological testing conditions. Despite the fact the samples sintered at 750$^\circ$C contain about 50 wt% of $\beta$ phase, their friction coefficient is close to that of Al–Cu–Fe quasi-crystals.
