Study on the Complex of Sodium Tungstate and Urotropine as Inhibitors Against Stainless Steel Corrosion in the NaCl Solution

摘要：

The corrosion weight loss method and polarization curve measurement were conducted to study the effects of the complex inhibitor of sodium tungstate and urotropine on the corrosion of 304 stainless steel in the 3.5％ NaCl solution. The results indicated that the complex inhibitor has good synergistic inhibitory effect for stainless steel in the NaCl solution. Combining sodium tungstate and urotrpine at a total concentration of 500 mg/L, when the mass ratio of sodium tungstate to urotrpine was 7:3, the inhibitory effect was optimum. In addition, the probable inhibitory mechanism was analyzed.
