摘要	Lanthanum nitrate has been investigated as corrosion inhibitor of X70 pipeline steel in 3.0 (wt.%) NaCl solution using electrochemical techniques such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) in conjunction with scanning electron microscopy (SEM) and energy dispersive X-ray detector (EDX) techniques. The results showed that La(NO3)(3) belonged to the film-formed mixed inhibitors, which can form a compact network over the whole surface of X70 pipeline steel. The inhibition effect of La(NO3)(3) on X70 steel reinforced with the increase of the concentration itself. The EDX analysis showed that lanthanum ions were found to participate in the network film formed on the sample surface.
