| description |
Based on the study of current-voltage dependences during the co-deposition nt electrical reduction of rhenium and molybdenum from sulfuric acid on a Pt electrode, conditions for deposition of alloy nanocoatings of the Re-Mo system were established. The influence of various factors, such as the content of components in the electrolyte, current density, temperature, acidity of solutions, etc., on the composition and quality of coatings was studied. It was established that with an increase in the content of rhenium in the electrolyte and increase of current density, the content of rhenium in the alloy is increased. The composition and morphology of Re-Mo thin films electrodeposited on a platinum electrode were analyzed. The phase composition of the obtained films was determined by XRD using a diffractometer, and the study of the morphology of Re-Mo films on platinum and nickel substrates was performed using a scanning electron microscope. Based on this study, the optimal conditions for the deposition molybdenum with rhenium and the required composition of the electrolyte were selected. For the obtaining rhenium-molybdenum alloys containing 50-80 wt.% Re, the following electrolyte composition can be recommended: 0.0015M Na2MoO4 + 0.0035M KReO4 + 2M H2SO4, pH 0.4; t = 75°C, electrode - Pt.
