ժҪ The self-assembled monolayers (SAMs) of 1-tetradecylphosphonic acid (TDPA) formed on the 430 stainless steel (SS430) were studied. Surface and morphological characterizations were studied by Fourier transformed infrared spectroscopy (FTIR), water contact angle measurement and atomic force microscopy (AFM). And the electrochemical study on the corrosion inhibition of the SAMs was performed by polarization curve and electrochemical impedance spectroscopy (EIS) for evaluating the corrosion protection of the SAMs. The results show that TDPA was able to form a film spontaneously on the SS430 surface and the hydrophobic SAMs could protect SS430 from corrosion effectively. In addition, the oxide surface formed by the heat pretreatment could accelerate the rate of adsorption, but had little effect on improving the inhibition efficiency.
