چکیده:

The new anti-corrosion Nano Melamine Formaldehyde (NMF) compound were formulated utilizing the Melamine Formaldehyde (MF) resin which was synthesized by addition of proper amount of formaldehyde to melamine, mixed with a novel ceramic powder which was extracted from corn cob containing SiO2 nano particles. These products provide a high level of protection for steel subjected to a broad range of corrosive attack especially in chloride ion environment unlike conventional methods, such as filming amine-based corrosion inhibitors. The synthesized inhibitor works immediately with a self-replenishing protective layer.The electrochemical standard corrosion tests and the surface examination using Scanning Electron Microscope (SEM) of steel specimens immersed in 3.5%Wt NaCl solutions with and without inhibitor at room temperature were carried out to investigate the inhibition effect of the synthesized nano inhibitor. Several evaluations were performed when corrosion inhibitors were added into electrolyte containing3.5%Wt NaCl. The results, which include the corrosion and electrochemical testing data, show that tested corrosion inhibitors are generally effective.
