Effect of Temperature on Sacrificial Anode Protection of Silicone Aldehyde Coated Water Cooler
In order to obtain boundary parameters for sacrificial anode protection of water coolers at different temperatures,constant potential and potentiodynamic scanning methods are used to study the electrochemical performance of AZ31B magnesium alloy sacrificial anode,10#carbon steel,and 10#carbon steel protected by silicon aldehyde coating in simulated cooling water at different temperatures.The experi-ments results indicate that the temperature has a significant impact on AZ31B magnesium alloy,and the corrosion potential increases with temperature.The silicone aldehyde coating has good protective performance with a low cathodic polarization current density within the tem-perature range of 30～90℃.It can provide good protection for the water cooler combined with the sacrificial anode.The boundary condi-tions required for the subsequent sacrificial anode protection simulation calculation of the water cooler were obtained through the cathodic po-larization curves of 10#carbon steel and silicon aldehyde coated steel,as well as the anodic polarization curves of AZ31B magnesium alloy.
