The effect of denitrifying Fe-oxidizing bacteria TPH-7 on corrosion inhibition of sodium molybdate
Source abstract
Abstract
Abstract The corrosion process characteristics in the presence of thermophilic strain TPH-7 were investigated. The results showed that (1) by adding Na 2 MoO 4 to the sterilized solution, the steel could be well protected with the increasing of the concentration from 0 to 100 mg/l, which caused the decreasing of corrosion current; (2) in the solution with strain TPH-7 and Na 2 MoO 4 , corrosion product formed and corrosion current decreased slightly. Based on the SEM observation, strain TPH-7 would adhere to the steel surface to interfere with the corrosion inhibition process of steel by molybdate. Therefore, 100 mg/l Na 2 MoO 4 could not inhibit the MIC caused by strain TPH-7.
