Some 4-phenylthiazole derivatives were tested as corrosion inhibitors for 304L stainless steel in 3.0 M HCl using weight loss and galvanostatic techniques. The results showed that the inhibition efficiency increases with increasing the concentration of the 4-phenylthiazole derivatives. Polarization measurements showed that these derivatives act as mixed-type inhibitors. The adsorption of these inhibitors on the surface of stainless steel follows Temkin’s adsorption isotherm and kinetic model. The effect of temperature on the corrosion was investigated by the weight loss method and some thermodynamic parameters were calculated. The synergistic influence caused by thiocyanate ion on the inhibition of corrosion of 304L stainless steel in 3.0 M HCl in the presence of 4-phenylthiazole derivatives has been studied using weight loss method. The inhibition action of these 4-phenylthiazole derivatives was discussed in terms of its adsorption on the metal surface.
