中文摘要:
      目的 研究硝酸锌、钼酸钠及三聚磷酸钠之间的协同缓蚀作用机理,使其在性能上实现互补。方法 以酸性高锰酸钾溶液为基础,通过极化曲线和失重法实验,研究 3 种缓蚀剂对 1Cr18Ni9Ti 奥氏体不锈钢的协同缓蚀作用。 结果 硝酸锌和三聚磷酸钠以抑制不锈钢的阴极反应为主,钼酸钠则主要抑制不锈钢的阳极反应。 硝酸锌与钼酸钠表现出明显的拮抗作用,导致缓蚀效果变差。 只有当三聚磷酸钠加入后,三者之间才表现出了良好的协同作用,使总的缓蚀性能达到最优,复配后的缓蚀效率可以达到90% 以上。 结论 硝酸锌、 钼酸钠及三聚磷酸钠之间存在良好的协同缓蚀作用, 可以明显降低1Cr18Ni9Ti 不锈钢在酸性高锰酸钾溶液中腐蚀速率,从而延长设备的使用寿命。
英文摘要:
      Objective To investigate the synergistic inhibition effect of zinc nitrate, sodium molybdate and tripolyphosphate and make the property of these inhibitors to complement each other. Methods Based on acidic potassium permanganate solution, the synergistic inhibitive effect of zinc nitrate, sodium molybdate and tripolyphosphate on corrosion of 1Cr18Ni9Ti stainless steel was investigated by means of polarization curve and weight loss method. Results Zinc nitrate and tripolyphosphate could mainly inhibit the cathodic process of 1Cr18Ni9Ti stainless steel, while sodium molybdate mainly suppressed its anodic reaction. Since zinc nitrate and sodium molybdate had significantly antagonism with each other, the effectiveness of corrosion inhibition became poor. These three corrosion inhibitors exhibited a good synergistic effect after tripolyphosphate was added, which lead to the optimal performance of the overall effectiveness of inhibitors and the efficiency of corrosion inhibitor could reach higher than 90% . Conclusion There was a good synergistic effect among zinc nitrate, sodium molybdate and tripolyphosphate in corrosion inhibition of metals. The corrosion rate of 1Cr18Ni9Ti stainless steel could be significantly reduced in acidic potassium permanganate solution and the life of the equipment could be extended.
