摘要：

O-methoxybenzaldehydebenzoylhydrazone (O-MBH) and bis-(o-methoxybenzaldehyde)-thiocarbodihydrazone (O-MTH) were synthesized. The O-MBH and O-MTH effects on the inhibition of copper corrosion in 3.5% NaCl solution were investigated. Electrochemical measurements showed that the addition of O-MBH and O-MTH decreased the corrosion parameters of copper in the test solutions. The weight loss experiments indicated that O-MBH and O-MTH decreased the corrosion rate of copper. The data pointed out that O-MBH and O-MTH inhibit the copper corrosion in NaCl solution with inhibition efficiency in the order of O-MTH > O-MBH.
