The influence of the ultrasound on corrosion resistance of chromium-dioxide silicon nano-composition electrolytic coatings (nano-CEC) in solutions of the different concentrations of nano-particles of silicon dioxide at temperatures 293, 303, 313 K has been investigated. The research showed that the electroplating of chromium-dioxide silicon nano-CEC on steel St.3 enlarges its corrosion resistance tenfold. The least corrosion resistance has nano-CEC, which got under constant ultrasound influence, and the most - whi...

Electrodeposition of composite coatings based on cobalt alloys from citratepyrophosphate electrolytes is investigated. The features of the co-reduction of cobalt with refractory metals (Mo, W, Zr) directly from the electrolyte solution are due to the mutual influence of thermodynamic and kinetic characteristics of alloy-forming components. Modern electrochemical technologies for surface treatment of titanium alloys to create protective, antifriction, dielectric, and catalytically active materials are considered. T...
