The nickel – phosphorus – copper functional coating was deposited on aluminum alloys substrate by chemical deposition method from malonate­glycinate nickel plating solution. The chemical and phase coatings composition was studied by X­ray fluorescence and X­ray phase analyze. Thermally stimulated phase transitions in deposited Ni – P – Cu coating w...

Epoxy based composites filled with RhB-loaded TiO2 containers were prepared. SEM, EDX mapping, and Raman spectroscopy showed a uniform distribution of the TiO2 particles in the polymeric matrix. The sensitivity of the composites to UV irradiation was studied. Efficiency of the composite decolorization was found to depend on the amount of RhB-loaded...

The study is devoted to the electronic properties and structure of bismuth films obtained by electrodeposition from high-speed perchlorate electrolyte. Polycrystalline samples were synthesized in acidic perchlorate electrolyte under the (0.18 – 70.0) mA/cm² cathode current density and annealed at 265 oC in the He gas atmosphere. The structure, micr...

The influence of the duration of etching of a magnesium substrate from the MA2-1 alloy on the morphology and ad-hesion properties of a chemically deposited nickel – phosphorus coating has been studied. It is shown that the etching of the substrate in a mixture of chromium anhydride and nitric acid leads to the formation of an oxide chromate film o...

Common types of electrical contact materials are considered. Nickel-based coatings with non-metallic additives (bo-ron, phosphorus) as electrical contact materials are proposed. The electrical and mechanical properties of nickel-based coatings were studied for various methods of their formation. An increase in the transition resistance and a de-cre...

The thermal protective ability of electrochemically deposited Ni and Ni – B coatings was investigated with the aim of their potential application in the production of lamella-type under-die coolers. It has been established that all studied nickelbased coatings retain thermal stability when heated in an air atmosphere in the temperature range from 5...

Light absorbing materials are of practical importance in the production of optical devices in aerospace technology. A new method of light absorbing coatings preparation on the basis of electrodeposited nickel-phosphorus coatings has been proposed. Modification of the electrolyte for nickel-phosphorus plating by the addition of saccharine allowed pr...

The electrodeposition of bismuth films from acid perchlorate electrolyte was investigated. The influence of various factors on the discharge process of bismuth ions has been studied. The effect of an acridine dye on the structure and morphology of the films was established. It was shown that the presence of an acridine dye in the bismuth electr...
