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...

It is known that one of the methods for purifying gas fraction from hydrogen sulfide is amine treatment. Various types of amines are used to remove hydrogen sulphide, carbon dioxide and carbon dioxide from petroleum gases. The choice of specific amine depends on the needs of the process. Mono-ethanolamine (MEA) (C2H4OH) NH2 and diethanolamine (DEA) (C2H4OH) 2NH are commonly used. Both are ammonia derivatives. To develop recommendations on the choice of material from which to make equipment for amine plants, compar...
