تحسين الحماية التاكلية للفولاذ باستخدام طلاءات المتراكب النانوي PMMATiO2

الملخص EN

In this study polymer based nanocomposite coatings were prepared from Poly methyl methacrylate (PMMA) reinforced by TiO2 nanoparticles with average particle size of 75 nm and with different percentage (0, 0.5, 1.0, 1.5, 2.0 wt.%).

The coatings were applied on carbon steel sheets by dip-coating method.

The chemical composition of the nanocomposite coatings was investigated by FTIR spectroscopy.

Corrosion behavior of the coated carbon steel has been done by immersion method in acid and salt solutions at room temperature.

The weight loss and corrosion rate as a function of exposure time have been measured as an indication for the effect of the carbon steel by different corrosive media.

Experimental results confirm that the PMMA/TiO2 nanocomposite coatings enhanced the corrosion resistance of steel in comparison with pure PMMA coatings in both acid and salt corrosive media.
