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 – which was received without ultrasound influence. These results are explained by the fact that nano-CECs deposited under ultrasonic action are obtained with increased defectiveness, with a large number of through channels penetrating from the surface to the protected steel, through which the corrosive medium penetrates to the base-coating interface. At this boundary, they cause intense corrosion of the base, i.e. become. The products of this corrosion, as a result of their large specific volume, but through the same channels go outside, to the surface of the nano-CEC, creating visible corrosion lesions.
