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。
The corrosion inhibition effect of composite amino acids derived from beans on A3 steel was investigated. The experimental results show that the inhibitory coefficient is lgr = 2.41 + 0.46lgC when the corrosion inhibitor is less than 1.0% in hydrochloric acid medium at room temperature. The main effect is to suppress the cathodic process, showing a negative catalytic effect. When the amount of addition> 1.0%, the corrosion potential began to shift. After the system is warmed, the corrosion inhibition mainly hinders the anodic dissolution.
