| 摘 要： | 采用电化学方法，研究了硫脲、十二烷基硫酸钠（SDS）、聚天冬氨酸（PASP）及它们的复配物在自来水中对AZ91D镁合金的缓蚀性能。结果表明：聚天冬氧酸和硫脲复配比其它组合缓蚀剂的效果好，20℃时，在实验范围内，当体系添加这两种物质浓度分别为0．05g／L，添加总量为0．1g／L时．缓蚀率达到了81．7％，

| Abstract: | Electrochemistry methods are used to study the corrosion inhibition performance of thiourea,sodium dodecyl sulfate(SDS),and polyaspartic acid(PASP) on AZ91D magnesium alloy in water.The results show that inhibition efficiency for adding the polyaspartic acid and thiourea is better than other combination of corrosion inhibitors.The inhibition efficiency is 81.7% at 20℃ when it is 0.05 g/L of polyaspartic acid and thiourea respectively. |
