چکیده
|
Different amounts of nanoclay were incorporated into the acrylic resin matrix at 0, 1, 3, and 5 wt.% loadings. the coatings were applied on low carbon steel plates. optical microscopy, sedimentation test, transmission electron microscopy, and xray diffraction were employed to investigate the dispersion of nanoclay in matrix. the corrosion resistance of coatings was evaluated by electrochemical impedance spectroscopy, polarization measurement, and salt spray test. in addition, pulloff and crosscut tests were used for the assessment of coating adhesion to the substrate. the results indicated that the anticorrosive properties of the acrylic resin were obviously increased by the addition of nanoclay. the nanocomposite coatings containing 3 wt.% clay showed the best corrosion resistance. finally, the nanocomposites containing 1 and 3 wt.% showed the highest adhesion to the substrate.
