摘　　要：从浸泡在海水中的B30合金表面形成的微生物膜中提取分离出产氨菌,并研究产氨菌对B30在海水中腐蚀行为的影响。实验结果表明:产氨菌的存在使B30腐蚀电位明显负移,并使其发生严重的局部腐蚀;产氨菌产生的氨气及其新陈代谢活动共同作用导致B30的严重局部腐蚀。Effects of ammonia producing bacteria on corrosion of B30 were studied, using microbiological, electrochemical and SEM technologies. The corrosion potential of B30 shifted from-300mV to -600mV（vs. SCE） and serious localized corrosion was observed in the presence of ammonia producing bacteria, indicating that metabolism of ammonia producing bacteria together with ammonia produced by it led to serious corrosion of B30.
