| 摘 要： | 当模拟水介质的pH在7~9之间,随着pH值的增大,B30铜镍合金的耐蚀性能增加;pH大于9时,B30铜镍合金的耐蚀性能又随pH的增大而降低.模拟水介质的温度升高,氯离子或硫离子浓度的增加,都会使B30铜镍合金的耐蚀性能降低.在模拟水中加入绿色水处理缓蚀剂复配聚天冬氨酸40 mg/L时,对B30铜镍合金具有明显的缓蚀效果.

| Abstract: | The inhibition effects of environment-friendly inhibitors of the complex of PASP and Na2WO4 for B30 Cu-Ni alloy corrosion are studied.The results show that with the concentration of the sulfur ion and chloride ion of the simulated water,the corrosion is increasingly strengthened.Moreover,the increased temperature also accelerates the corrosion velocity for B30 Cu-Ni alloy in simulated water.The resistance of Cu-Ni alloy to the corrosion is enhanced with the increasing pH of the simulated water in the range of pH 7 and pH 9.When the pH exceeds 9,the increase of pH leads to a decrease of resistance to corrosion for B30 Cu-Ni alloy.With the total concentration of 40 mg/L for the complex inhibitors,the optimum complex ratio of PASP to Na2WO4 is 1:1 and such a complex gives a good inhibition effect. |
