摘要: Purpose – The purpose of this paper is to investigate how improve the corrosion inhibition behavior molybdate‐based inhibitors for mild steel, using organic compounds containing a phenyl ring together with nitrite agent. As picrate contains three substituent anions, it used as an compound. In study new inhibitor was introduced composition 60 ppm molybdate/40 ppm nitrite/20 ppm picrate. Inhibition efficiency molybdate alone and on uniform steel in stimulated cooling water assessed.Design/methodology/approach carbon (SCW) assessed by electrochemical techniques such potentiodynamic polarization, impedance (AC impedance) measurements weight loss determinations at room temperature. Studies electro...
