“…However, they are susceptible to different forms of corrosion such as pitting [1] and dezincification. So, the addition of small amounts of tin [2] and other elements such as arsenic, antimony and phosphorous [3,4] improves the dezincification resistance of brasses in various aggressive environments [5].…”

The effect of triazole (TR), 3-amino-1,2,4-triazole (ATA) and cetyltrimethylammonium bromide (CTAB) on the inhibition of brass corrosion in simulated cooling water system has been studied using electrochemical measurements, scanning electron microscopy (SEM) observations and energy dispersive X-ray (EDX) analysis. The potentiodynamic polarization study reveals that these inhibitors inhibit both cathodic and anodic reactions, indicating a mixed-type control of inhibition and their inhibition depend on the nitrogen number in their structure. It shows that the ATA is the best inhibitor. The interference between CTAB and TR derivatives against corrosion has been also studied. So, a large passive current plate is observed directly from the corrosion potential in the presence of formulation. In addition, the operational parameters effect on the performance of this formulation is also investigated. It shows that its inhibition efficiency increases with pH, immersion time and the presence of corrosion products and takes its performance by increasing in temperature. The SEM/EDX data confirm that the formulation is a corrosion and scale inhibitor.

3,5-Diamino-1,2,4-triazole Schiff base derivatives and their inhibition efficiency, based on the effect of changing functional groups, were reported to establish a relationship between inhibitor efficiency and molecular structure using weight loss method, electrochemical and Fourier transform infrared spectral techniques. It was found that the molecules containing more electron donating groups have higher inhibition efficiency than the corresponding compounds with low electron donating groups.The results indicate that the order of inhibition efficiency of the triazole and its Schiff bases in solution and the extent of their tendency to adsorb on mild steel surfaces are as follows: vanilidine 3,5-diamino-1,2,4-triazole [ furfuraldine 3,5-diamino-1,2,4-triazole [ anisalidine 3,5-diamino-1,2, 4-triazole [ 3,5-diamino-1,2,4-triazole.

Abstract:A single electrodeposited film of 6-(3-triethoxysilylpropyl)amino-1,3,5-triazine-2,4-dithiol monosodium (TES) on a copper alloy surface was prepared by the galvanostatic method, then octyl-triethoxysilane (OTES) or hexadecyl-trimethoxysilane (HDTMS) was used to modify the electrodeposited film by the self-assembled technique to fabricate the complex film. The electrodeposition process was inferred by cyclic voltammetry. The single and complex films were characterized by means of contact angle, cyclic voltammetry, Fourier transform infrared spectroscopy (FT-IR), potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM). The results showed that the contact angle of the complex film covering the copper alloy surface was up to 118.1˝compared with 89.4˝of the bare copper alloy. The cyclic voltammogram, polarization curves and EIS indicated that the anti-corrosion performance of complex film was better than that of single electrodeposited TES film, and the protection efficiency was up to 90.2%.
