Effect of Molybdate Anions On Corrosion Behavior of Stainless Steel 304 In 0.1M Nacl Solution
The research was aimed to study the effect of molybdate ions (MoO4=) on corrosion behavior of SS 304 in 0.1M NaCl solution with six different concentration of molybdate ion in the range (0.01 – 0.3 M) at room temperature. Corrosion parameters such as open circuit potential (Eocp), corrosion potentia...

| description | The research was aimed to study the effect of molybdate ions (MoO4=) on corrosion behavior of SS 304 in 0.1M NaCl solution with six different concentration of molybdate ion in the range (0.01 – 0.3 M) at room temperature. Corrosion parameters such as open circuit potential (Eocp), corrosion potentials (Ecorr), corrosion current density (icorr) and Tafel slops (bc & ba)were measured and discussed. The polarization resistance (Rp) and rate of the corrosion in (mpy) values were calculated, the protection efficiency (P%) in solution NaCl containing molybdate anions was also estimated. All these parameters indicated role of molybdate as inhibitor material of corrosion SS 304 in NaCl solution and exhibit that the 0.03M MoO4 -2 has the best values of Rp, rate (mpy) and P%. The inhibition by molybdate was observed through adsorption process and formation of oxide layer on surface of Stainless Steel. |
