    • Abstract
  • The inhibition effects of sulfourea on HR-2 stainless steel in acidic sodium chloride solution were studied by scanning electrochemical microscopy (SECM) and polarization curves. The results show that the corrosion inhibition of sulfourea is obvious. When the concentration of sulfourea increased to 0.75 mmol/L, the corrosion inhibition became stable; the corrosion potential changed tinily. According to EI-Awady model, the sulfourea adsorption is monomolecular layer on the surface of the stainless steel, one sulfourea molecular adsorb on multiple active points.
