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.
