A B S T R A C TThe present investigation highlights the role of solution hydrodynamics on the deposition of calcium sulfate scale on copper substrate. The study was carried out using a Rotating Cylinder Electrode (RCE) system at various pre-set rotational speeds, at 60 and 70 C on 120 and 600 grits polished cylindrical specimens. The effects of temperature, surface roughness, and flow conditions on the deposition of calcium sulfate scale on copper substrate are presented. The results indicate that the solution hydrodynamics play an important role on the rate of deposition of calcium sulfate scale on copper specimens. In addition, the analysis of scaling data further corroborated well with the theoretically predicted diffusion controlled process. Morphology of deposited crystals was obtained from scanning electron microscope (SEM) micrographs and composition was determined with energy dispersive X-ray spectrometer (EDS) method. SEM revealed prismatic needle-and rod-like crystals growth at nucleation sites branching out randomly over the substrate. The secondary growth on the already existing primary crystals of CaSO4 was also seen. EDS confirmed the composition included Ca and S as expected. Furthermore, X-ray diffraction (XRD) analysis of scale showed hemi-hydrate (CaSO 4 Á1/2H 2 O) form of gypsum.

“…The rotating cylinder electrodes (RCEs), pipe segments, concentric pipe segments, submerged impinging jets and closecircuit loops have been used as hydrodynamic systems in order to study the corrosion phenomenon under turbulent flow conditions [6][7][8][9][10][11][12]. The use of the RCE, as a laboratory hydrodynamic test system, has been gaining popularity in corrosion studies under turbulent flow conditions [12][13][14][15].…”

A corrosion study of API X52 steel was carried out in natural seawater with several concentrations of a corrosion inhibitor (10, 100 and 200 ppm) using a rotating cylinder electrode (RCE) to control the hydrodynamic conditions at environment temperature, atmospheric pressure and 24 h of the exposition time. The rotation speed used was 1000 rpm (turbulent flow). The electrochemical techniques used in the corrosion studies were: linear polarisation resistance (LPR), electrochemical impedance spectroscopy (EIS) and polarisation curves (PCs). The superficial analysis was made using a scanning electron microscope (SEM).
