摘　　要：运用失重法及电偶电流的测量评定了ＢＭＡＴ对３１６Ｌ／碳钢组成的电偶对在５％（质量分数）ＨＣｌ中的缓蚀性能，结果表明，ＢＭＡＴ能很好地抑制此电偶对的腐蚀；极化曲线的测量表明：ＢＭＡＴ既能抑制发生在电偶对中碳钢阳极溶解反应Ｆｅ→Ｆｅ２＋＋２ｅ，又能抑制不锈钢阴极析氢反应２Ｈ＋＋２ｅ→Ｈ２。Inhibition effect of BMAT on galvanic corrosion of stainless steel carbon steel in 5% HCl was assessed by weight loss measurement and testing galvanic current. The result shows that BMAT can inhibit galvanic corrosion of the couple. Testing polarization curves shows that BMAT can simultaneously inhibit carbon steel anode dissolving reaction Fe→Fe 2+ +2e and stainless steel cathode hydrogen evolution reaction 2H ++2e→H 2.
