摘　　要：研制了一种新型YWY有机膦缓蚀剂,应用重量法、电化学方法及扫描电镜等手段对合成的有机膦缓蚀剂YWY在苦咸水条件下的缓蚀性能及其缓蚀机理进行了研究。实验表明,该缓蚀剂可与碳钢表面螯合形成致密的覆盖膜,表现出明显的阴极型缓蚀剂特征。在缓蚀剂浓度大于12mg/L时,可使氯离子浓度大于30000mg/L的苦咸水/碳钢体系腐蚀速率降至0.03mm/a以下,达到国家耐蚀级标准。A novel YWY-typed organic phosphorus corrosion inhibitor was synthesized and researched by weight corrosion value, potentiodynamic method and SEM under the condition of bitter salt water. The results showed that, with the inhibitor YWY, a compact overlayer film was obtained on the metal surface and YWY showed cathode corrosion inhibitor. When the concentration of YWY is over 12 mg/L, and C1^- is more than 30000 mg/L, the corrosion rate is less than 0.03mm/a, reach the Chinese corrosion resistance standard.
