Paper Title:
Corrosion Inhibition of 304L Stainless Steel by Dicyclohexyl Thiourea in HCl Solution
  Abstract

At four different temperatures, by potentiodynamic polarization curve, the inhibiting effect of dicyclohexyl thiourea (DCTU) on the corrosion behavior of 304L stainless steel in 2 M hydrochloric acid solution was investigated. The result indicated that DCTU acted as an efficient anodic inhibitor for the corrosion of 304L SS. Excellent inhibition efficiency was evident in the acidic solution and found to vary with temperature and concentration of the inhibitor. The adsorption of this compound on the 304L SS surface was found to obey Temkeins adsorption isotherm and the inhibition was governed by chemisorption mechanism. The deduced thermodynamic parameters of adsorption revealed a strong interaction and spontaneous adsorption of DCTU on the metal surface.
