Anticorrosion properties of pigments based on ferrite coated zinc particles
Original language description
The paper deals with a new anticorrosion pigment synthesized on a core-shell basis. For its syntheses is used a starting substance that form the lamellar shaped core, namely lamellar zinc. While the cover of the core is represented by zinc oxide, which is in fact partly oxidized lamellar zinc core, and is created during the calcination of the pigment. The compound that forms the topper layer of the core a ferrite is also formed during the calcination. Formula of the prepared pigment is then defined as MexZn1-xFe2O4/Zn and the formula of thin ferrite layer is MexZn1-xFe2O4 (where Me = Ca, Mg). Due to its shape this anticorrosion pigment includes another anticorrosion effect, so called ?barrier effect?. The mechanism of anticorrosion effect, corrosion efficiency and mechanical properties were investigated of epoxy-ester paint systems with PVC at 10%. Mechanical tests were performed to determine adhesiveness and mechanical resistance of paints. And accelerated corrosion tests were carried
