Název v původním jazyce

Synthesis of ZnxMgyAl2O4 spinels for use protective coatings

Popis výsledku v původním jazyce

Purpose was to synthesize lamellarly shaped anticorrosion pigments with a chemically active layer whose core consists of metal aluminum on which a thin spinel film is synthesized. Pigments were synthesized: MgAl2O4/Al; Mg0.8Zn0.2Al2O4/Al; Mg0.6Zn0.4Al2O4/Al; Mg0.4Zn0.6Al2O4/Al; Mg0.2Zn0.8Al2O4/Al; and ZnAl2O4/Al. The prepared pigments were characterized by means of X-ray diffraction analysis and scanning electron microscopy. The lamellar shape of the particles as well as good-quality coverage with a thin spinel layer was identified in the prepared pigments. All of the synthesized pigments exhibit good anticorrosion efficiency in epoxy coatings. Compared to lamellar kaolin and metal core of aluminum without coverage, the protective function of the synthesized pigments in coatings is demonstrably better. The synthesized pigments find convenient applications in coatings protecting metal bases from corrosion.
