ملخص المقالة :

The influence of the concentration of1-H-benzoteriazolon the corrosion of 316 stainless steel (SS) in chloride acid 1M solutions was studied. The potentiodynamics polarization and scanning electron microscopy (SEM) have been used. The inhibition efficiency increased with an increase in the concentration of1-H-benzoteriazol.The adsorption of1-H-benzoteriazol onto the SS surface occurs according to the Langmuirisotherm. The corrosion kinetic parameters of 316 stainless steel and thermodynamicadsorption parameters for1-H-benzoteriazolwere determined and discussed.
