Fig. 3: Morphology of steel in seawater simulators at different culture stages (25, 55 and 85 days) with/without crude oil exposure.

From: Microbiologically influenced corrosion of steel in coastal surface seawater contaminated by crude oil

Fig. 3

Surface morphology of steel samples was visualized using SEM and CLSM techniques after removing the corrosion products. Sa: Roughness coefficient. “With Oil”: With crude oil amendment; “No Oil”: Without crude oil. T1: 25 days; T2: 55 days; T3: 85 days.
