Abstract

In this work, an anticorrosion coating based on acrylic varnish and nanosized zinc oxide powder obtained in a Nanospray Drying B-90 apparatus was obtained and tested. Using the potentiodynamic polarization method, it was established that the efficiency of coating protection is 98 and 81% in acidic and neutral environments of dilute electrolytes, respectively. Based on X-ray phase analysis and optical and electron microscopy, it was shown that the addition of zinc oxide increases the number of adhesion centers, resulting in better adhesion of the polymer coating to the substrate and preventing the manifestation of the Fe3C phase on the surface.
