Sažetak
Incorporating an anticorrosive component, such as nanoparticles, into organic coatings presents a challenged for researchers because nanoparticles tend to form agglomerates. The aim of this work is to improve and compare two methods of mixing nanoparticles into epoxy paints. The mixing of 1% aluminum nanoparticles was carried out by a mechanical and ultrasonic process. The surface of the nanocomposite coating was analyzed using a scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). The corrosion behavior of the epoxy coating with and without nanoparticles was examined using electrochemical impedance spectroscopy (EIS) in a 3.5% NaCl solution. Electrochemical testing of the coating was completed with the use of a scanning electrochemical microscope (SECM). Electrochemical surface analysis of the coating enables a topography of monitoring the degradation of the coating. The results show that the nanocomposite with 1% aluminium nanoparticles prepared using an ultrasonic homogenizer has better anticorrosion properties than the nanocomposite prepared by mechanical stirring.
