丙炔醇对铝阳极电化学性能的影响
Effect of Propargyl Alcohol on Electrochemical Behavior of Aluminum Anode in Alkaline Solution
摘要
Abstract
To improve corrosion-inhibition and activation properties of aluminum, effects of additives ( propargyl alcohol) on electrochemical properties of aluminum anode(99. 999％ )in 4 mol/L KOH solution were studied by using electrochemical methods. The results show that corrosion of aluminum is inhibited, corrosion-inhibition ratio is 85. 35％ and that Eocp is also improved when 0. 5％ propargyl alcohol is added int0 4 mol/L KOH. It not only decreases corrosion rate (93. 21％ of corrosion-inhibition ratio) , but also increases activation properties of aluminum and that Eocp, reaches - 2. 011 V when 0. 5％ propargyl alcohol is added into "4 mol/L KOH + saturated Ca ( OH)2".关键词
