几种植物的茎叶作为缓蚀剂对钢的阴极极化行为的影响

On Effects of Some Plant Corrosive Inhibitorson Cathodic Polarization of Steel

恒电位法测试钢在分别加入４ 种浓度３ 种缓蚀剂的３ 种腐蚀性介质中的阴极极化曲线， 通过对极化曲线的分析， 研究所用缓蚀剂对钢在其所处介质中的阴极极化行为的影响试验结果表明： ３ 种缓蚀剂对钢在３ 种腐蚀性介质中的阴极过程均有抑制作用，

The cathodic polarized current for steel in three kinds of corrosive liquids are determined Three kinds of corrosive inhibitor are added into these corrosive liquids respectively The concentrationsofinhibitors are different Through analyzing the corresponding cathodic polarized curves ,the effects ofinhibitors on the cathodic polarized for steel are investigated The experimental data shows that all theinhibitors are effective to inhibitthe cathodic process of steelin the liquids and the effects depend on theamount of each inhibitor
