Corrosion behaviour of X65 carbon steel under the intermittent oil/water wetting: A synergic effect of flow velocity and alternate immersion period

The effect of flow on corrosion behaviour carbon steel under intermittent oil/water wetting was investigated by a newly-modified “alternate cell”, combining with the use potentiostatic polarisation, in-situ visualisation, contact angle measurements and scanning electron microscopy (SEM). time determined formation thin film electrode surface after transition immersion state. A short alternate period low velocity can increase ratio (oil to water time) efficiently mitigate corrosion, proposing logistic regression tendency between mitigation efficiency time.
