摘　　要：研究了镀膜工艺对复配十八烷胺缓蚀剂膜层抗腐蚀性能影响,并分析了膜层的腐蚀机理。结果表明,镀膜液pH=6的膜层腐蚀发生在微观缺陷上,pH=8～12的膜层腐蚀发生在晶界上;随着镀膜液pH值升高,膜层结构完整,抗腐蚀性能增强;在镀膜液pH=8～12时,随镀膜温度升高,膜层的组织致密,抗腐蚀性能增强。镀膜液pH=10、镀膜温度250℃为复配十八烷胺缓蚀剂最佳镀膜工艺。The influences of the coating process on the the corrosion resistance of octadecylamine corrosion inhibitor with surfactant mixture were studied,and the corrosion mechanism of the coatings was analyzed.The main results show that the microscopic defects of the coating are corroded when the coating solution pH=6,and the corrosion is corroded on the grain boundary of the coating when the coating solution pH=8～12.The coating＇s structure is integrity and the corrosion resistance increases with the increase of coating solution pH.The corrosion resistance of the coating enhances and its microstructure becomes dense with the increase of temperature.The best coating process of the octadecylamine corrosion inhibitor with surfactant mixture is coating solution pH=10 and coating temperature 250 ℃.
