“…The efficiency of Met as good corrosion inhibitor of copper attributes to the strong banding between copper surface and the formed film. Increasing the interaction of the molecule with the metal surface is explains as result of the Nitrogen atom (heteroatoms) in met molecular which give electrons of vacant d orbitals in the atom of copper [21,22]. Some recently laboratory studies were presented Met.…”

:The research aimed to evaluate the efficiency of three compounds from preferred corrosion inhibitors of copper artifacts to be used to protect silver artifacts. The compounds are Benzotriazole (BTA), L-methionine (Met.) and Sodium decanoate (NaC 10 ), each inhibitor was tested with and without Nano-alumina. The evaluation of these compounds was performed using the electrochemical measurements (Potentiodynamic (pt) and Electrochemical Impedance Spectroscopy (EIS)) and accelerated corrosion test with H 2 S gas and water resistance test within enclosed chamber. The treated silver coupons with studied inhibitors were examined using microscopes SEM, PM and AFM to appear some important features of the formed film. The study was carried out on manufactured coupons of the silver alloy with copper. The results revealed that BTA and NaC 10 in presence and absence Nanoalumina have good efficiency in the protection of the silver coupons in the corrosion conditions used in the tests.

“…The adsorption of these organic compounds by deferent centers of adsorption on the electrode surface makes a barrier for mass and charge transfers. This situation leads to a reduction in the double layer and a protection of the metal surface from the attack of the aggressive anions of the aggressive solution (Barouni et al, 2008;Emran et al, 2014).…”

The effect of cantaloupe juice and seed extracts on corrosion of cast iron in 1.0 M hydrochloric acid (HCl) solution using hydrogen evolution measurements (HEM) and mass loss measurements (MLM) were investigated. Cantaloupe extracts inhibited the corrosion of cast iron in 1.0 M HCl solution. The inhibition efficiency increased with concentration of the extracts. The adsorption of the inhibitor molecules on cast iron surface was in accordance to Langmuir adsorption isotherms. In absence of inhibitors, the corrosion rate of cast iron increases with HCl concentration. The fractional reaction order observed in HCl solution indicates the formation of intermediates through the dissolution process or multiple steps mechanism of cast iron dissolution in HCl solution.
