WebbHowever, when brass is exposed to a corrosive solution, it starts to corrode [31–34]. One of the effective ways to mitigate the corrosion of brass is to use imidazole corrosion inhibitors. In this study, 2-mercapto-1-methylimidazole (MMI with the chemical structure given in Figure1) is presented as a corrosion inhibitor for brass WebbNaval Brass. Naval brass is the classic marine, high-strength and corrosion-resistant alloy containing 60 percent copper, .75 percent tin and 39.2 percent zinc. It is widely used in marine construction where strong, corrosive-resistant and hard material is required and is suitable for both salt and fresh water applications.
