摘要：

Two new green volatile corrosion inhibitors namely oleic hydrazide benzoate (OHB) and oleic hydrazide salicylate (OHS) were synthesized. Their inhibition action was evaluated on corrosion of mild steel under a thin-film electrolyte consisting of simulated water using the weight loss, potentiodynamic polarization and electrochemical impedance methods. Atmospheric corrosion monitor cell (ACMC) was used to study the electrochemical properties of the inhibitors. The results of polarisation study show that OHB is anodic type and OHS is a mixed-type inhibitor. Oleic hydrazide benzoate (OHB) exhibited higher inhibition efficiency (89.31 % from potentiodynamic polarization) under vapour phase condition.
