Abstract

The issue of corrosion is a major problem on equipments failure and damage in industrial that would affect the safety and efficiency of the equipments. This study is focused on the corrosion of Nickel-Aluminiu-Bronze (NAB) alloy in aerated 0.1 M sodium chloride solution under hydrodynamic condition at 30°C. Hydrodynamic conditions are simulated by using rotating cylinder electrode (RCE) with five sets rotational speed which are 400, 800, 1200, 1600 and 2000 rpm. Electrochemical measurements such as open circuit potential, electrochemical impedance spectroscopy and potentiodynamic were used to study the corrosion mechanism and corrosion rate of NAB alloy. Results revealed that the formation of oxide layer and the corrosion rate were influenced by rotational speed. The value of open circuit potential is found to be shifted to more negative direction, the corrosion current density is increased while the charge transfer resistance decreased with rotational speed.
