丙炔醇对铝阳极电化学性能的影响OA北大核心CSCDCSTPCD
Effect of Propargyl Alcohol on Electrochemical Behavior of Aluminum Anode in Alkaline Solution
为了提高铝阳极材料的耐析氢腐蚀和活化性能,用失重腐蚀、电化学等方法研究了在4 mol/LKOH溶液中,丙炔醇对铝阳极(99.999%)电化学性能的影响,结果表明:添加0.5%丙炔醇,不仅使铝的析氢腐蚀速率降低(缓蚀率达85.35%),又能最大程度保持铝阳极的活性(超过铝在4 mol/L KOH溶液中的活性),开路电位Eocp负移达-2.033 V.此外,在"饱和Ca(OH)2+4 mol/L KOH"溶液中,添加0.5%丙炔醇时,铝的缓蚀率高达9…查看全部>>
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 rat…查看全部>>
