| 摘 要： | 考察了由豆类水解所得复合氨基酸对Ａ３钢的缓蚀作用。实验表明：在常温下盐酸介质中，当缓蚀剂＜１．０％时，抑制系数为ｌｇｒ＝２．４１＋０．４６ｌｇＣ主要表现为抑制阴极过程，呈现负催化效应。当添加量＞１．０％，腐蚀电位开始正移。体系升温后，缓蚀作用主要表现为阻止阳极溶解。

| Abstract: | The inhibiting action of complex aminoacid made by hydrolysis of soyabean on A 3 Steel in HCl show that the inhibition of cathodic reaction is negative catalysis with the inhibiting coefficient lgr= 2.41 0.46lgC at common temperature when inhibitor < 1.0%, while corrosion potential shift negatively when inhibitor > 1.0%; reversly the inhibiting anodic corrosion is main when temperature up. |
