摘　　要：采用恒电位极化曲线的测量方法，研究了苯并咪脞类化合物ＢＭＡＴ在质量分数为５％ＨＣｌ（下同）中对３１６Ｌ，１８８，２Ｃｒ１３的缓蚀机理，结果表明ＢＭＡＴ属于阴阳极混合控制型缓蚀剂，ＢＭＡＴ的加入抑制了析氢反应中氢离子的放电步骤；同时，本文还采用交流阻抗的测量方法。Inhibition mechansim of benzimidozole BMAT on 316 L, 188, 2Cr13 in HCl are studied by measurement of polarization curve, which shows that BMAT is a kind of mixtype inhibitor. BMAT can reduce the discharging rate of hydrogen ions. The measurement of A.C impedance gives the structure of interaction surface between stainless steel and HCl solution and (HCl+BMAT) solution.
