摘要

The analysis of hydrogen gas ingress during the corrosion of stainless steel inpickling acid such as 2N H_2SO_4 in the presence and absence of an ecofriendly inhibitorThiamphenicol[TPC] has been carriedout using mass loss, gasometric andelectrochemical studies. The antibiotic seems to be more effective in plummetingthe dissolution of steel in 2N H_2SO_4 .Potentiodynamic polarization clearly indicatedthat the inhibitor follows mixed mode of inhibition in 2N H_2SO_4 medium. Hydrogenpermeation and EIS measurements have confirmed that the present antibiotic checksthe dissolution of SS 304 efficiently in sulphuric acid . The theoretical values of EHOMO,ELUMO, ΔE and dipole moment in the presence of inhibitor established its effectiveadsorption on SS 304 metal surface.
