Article Preview

The corrosion inhibition of brass in simulated cooling water by complex of triethanolamine (TEA) and Na2WO4 had been investigated by means of electrochemical (AC impedance and dc polarization) techniques. The results indicated that both TEA and Na2WO4 were able to inhibit the corrosion of brass in simulated cooling water. TEA showed the best inhibition effect for brass corrosion at the TEA concentration of 30 mg/L, and the inhibition efficiency was 45.35%. At the total inhibitor concentration of 20 mg/L, the complex of TEA and Na2WO4 had a good synergistic effect, and the optimum ratio of TEA to Na2WO4 is 1:9, corrosion inhibition efficiency was 89.08%.
