dc.description.abstractThe phosphating of zinc surfaces, increasing their roughness and surface tension, provides high adhesion and a significant increase in the protective ability of subsequently applied organic coatings. This paper presents the results obtained in a study of combined coatings, including the formation of amorphous phosphate films on galvanized steel surfaces, followed by the application of layers of three type paints and varnishes. By means of gravimetric and physical-analytical methods, the influence of various factors such as concentration and temperature on the formation, composition and properties of the coatings obtained on zinc surfaces in phosphating solutions have been investigated. Coatings obtained at pH 4.0 are distinguished with best homogeneity and color density. The thickness of the coatings grows with increasing of temperature, at other conditions being equal. Тhe composition, structure, roughness and probable compounds of the obtained phosphate coatings have been determined by physical analytical methods. The phosphate coatings contain such elements as oxygen, phosphorus, zinc, molybdenum, nickel, which are probably combined as phosphate and oxide compounds.The phosphate films are X-ray amorphous, with indefinite habit and very well expressive relief. Using physico-mechanical methods, the adhesion, elasticity and impact strength of paint and varnish coatings on phosphated and non-phosphated zinc surfaces were measured.
