Abstract

The effect of surface roughness on the corrosion behaviour of low carbon steel in 4. M hydrochloric acid in the presence of corrosion inhibitor has been examined under laminar and turbulent flowing conditions. The corrosion rate increases with an increase in surface roughness in both the laminar and turbulent flow regimes. However, the effect of surface roughness is more pronounced under fully developed turbulent flow due to partial erosion of the inhibitor film caused by a high wall shear stress and turbulence eddies possessing relatively high kinetic energies.
