The theoretical foundations of the approach to the co-deposition of composite particles with multilayer matrices in nano- and submicron structuring with specified properties have been created. A method for accelerated testing of the stability of electrodes for hydrogen evolution in alkaline water electrolysis under conditions of voltage fluctuations and power outages by a renewable energy source has been created, which is closer to real conditions. The degradation resistance of single-layer and multilayer coatings [(Zn-Ni-Cu)/(Zn-Ni-Cu-М(ОН)2)]n under conditions simulating alternating voltage and disconnection was compared and the advantage of the latter was shown. The conditions for regeneration of electrode materials based on Zn-Ni-Cu alloys and their hydroxo compounds due to cycling in the hydroxide-oxohydroxide transition region were determined. The features of the formation of thin films of Mg-Si and Ti-Zr-Ni quasicrystals by the method of magnetron sputtering of the target and subsequent annealing in vacuum, their phase Product Description popup.authors Hrevtsov Viktor V.
