Abstract
Corrosion in industrial environments is one of the main factors limiting the life of materials. ZSM-5 has been synthesized and characterized by DRX and FTIR and its behavior as a studied corrosion inhibitor. In this study metal plates were covered with different zeolite films using the dip coating method. They were then introduced into NaCl solutions of different concentrations. The treated samples were studied by gravimetric and electrochemical methods to determine the corrosion inhibiting effect of their zeolite layers. The results show that the zeolite layers have exhibited high corrosion resistance and have great potential to become ecological alternatives to conventional coatings.
