ABSTRACT
In this study the effect of a new synthetic Schiff base namely bis -(2-hydroxy-3-methoxy)-1,6-diaminohexane salicylaldimine on the corrosion and dezincification of a 70/30 brass in 1M HCl has been studied using weight loss , electrochemical (polarization & impedance) and solution analysis techniques. Results obtained revealed that this compound is very good inhibitor and behaves as mixed type of inhibitor for brass 70/30 in this acid medium. Solution analysis and surface composition (weight%) of the alloy in the presence and absence of inhibitor by atomic absorption spectroscopy (AAS) and energy dispersive X-Ray analysis (EDAX) revealed the decrease in dissolution of both Cu and Zn in the presence of this inhibitor. The dezincification factor (Z) was calculated by using analysis solution.
Key Words: Inhibitor, polarization, impedance, dezincification,
corrosion.
