Using an electrochemical technique to study the effective variables on morphology and deposition of CaCO3 and BaSO4 at the metal surface

► Deposition of CaCO3 and BaSO4 at surface of a stainless steel electrode is studied. ► An electrochemical technique by the rotating disk electrode is used. ► Pressure, temperature, surfactant and pH are the effective parameters on the deposition. ► Using a flow condition at high pressure, nano size of the crystals is produced. ► Presence of monovalent cosalts in scaling solution considerably changes the morphology of crystal.
