Riboflavin-mediated enhancement on Desulfovibrio vulgaris corrosion of X80 steel welded joint in acidic soil solution
In this paper, the effect of riboflavin on SRB corrosion of X80 pipeline steel welded joint in acidic soil was investigated. The results showed that the metabolic activity of Desulfovibrio vulgaris (D. vulgaris) promoted the corrosion of welded joint and induced pitting corrosion in acidic soil, and the addition of riboflavin further aggravated the pitting corrosion. Among them, the localized corrosion susceptibility in the heat affected zone (HAZ) was consistently lower than that in the base metal zone (BM) and weld zone (WZ). In addition, riboflavin significantly increased the general corrosion rate of the welded joint.
