用失重法和极化曲线法研究了苯并咪唑类化合物（ＢＭＡＴ） 对碳钢或不锈钢在醋酸、硫酸、盐酸－ 氢氟酸－ 磷酸、自来水等腐蚀介质中的抑制作用，结果表明ＢＭＡＴ 能抑制由于Ｈ＋ 的去极化而引起的各种酸的腐蚀，并可提高不锈钢在含Ｃｌ－ 自来水中的抗点蚀能力．
The inhibitory effect of benzimidazole (BMAT) on carbon steel or stainless steel in corrosive media such as acetic acid, sulfuric acid, hydrochloric acid-hydrofluoric acid-phosphoric acid and tap water was studied by weight loss method and polarization curve method. The results showed that BMAT could inhibit Corrosion of various acids due to depolarization of H + and pitting resistance of stainless steel in Cl-tap water.
