【摘要】 本文合成了噻二唑类和咪唑啉类化合物,分别用失重法、极化曲线法和交流阻抗法研究了这两类化合物对金属在不同介质中的缓蚀作用,全文可分为综述部分和实验部分两大类。在综述部分,介绍了缓蚀剂的定义和分类,其中主要归纳总结了不同介质中常用的不同类型的铜和钢的缓蚀剂,并且讨论了不同介质中铜缓蚀剂的研究进展。在实验部分,我们研究了在酸性介质(1mol/L盐酸溶液)中四种席夫碱基咪唑啉化合物对A3钢的缓蚀作用和缓蚀机理,研究了在碱性介质(3%碳酸氢钠溶液)中五种5-烷基-2-氨基-1,3,4-噻二唑化合物对H62铜的缓蚀作用和缓蚀机理,研究了酸性介质(1mol/L盐酸溶液)中3-巯基-4-氨基-5-苯基-1,2,4-三唑(PAMT)、3-H-6-苯基-1,2,4-三唑并[3,4-b]-1,3,4-噻二唑(HPTT)、3-苯基-6-甲基-1,2,4-三唑并[3,4-b]-1,3,4-噻二唑(PHTT)和3-苯基-6-H-1,2,4-三唑并[3,4-b]-1,3,4-噻二唑(PMTT)对A3钢的缓蚀作用和缓蚀机理;用扫描电镜观察了四种席夫碱基咪唑啉化合物和PAMT、HPTT、PHTT、PMTT在A3钢表面的吸附行为,并与空白溶液中浸泡的A3钢表面进行了对比;又研究了温度对四种席夫碱基咪唑啉化合物、五种5-烷基-2-氨基-1,3,4-噻二唑化合物和PAMT、HPTT、PHTT、PMTT缓蚀性能的影响同时计算了相关的热力学常数
【Abstract】 In this paper, two types of compounds have been synthesized, including a series of thiadiazole compounds and Schiff-base imidazoline type compounds. Their corrosion inhibitions for different metals were studied by electrochemical impedance spectroscopy, potentiodynamic polarization curves and gravimetric measurements in this paper, which includes two parts: review section and experimental section.In review section, the definition of inhibition and the class of inhibition are presented in this paper, a primary overview is given of the development of the inhibition about copper and steel. In this paper, a detailed overview is given of the class of and the development of the inhibition of copper and steel.In experimental section, the inhibition of corrosion of A3 steel in hydrochoric acid solution by four Schiff-base imidazoline type compounds(BIA、BIOHA、BIMHA and BIMMA), the inhibition of corrosion of H62 copper in 3%NaHCO3 solution by 2-amino-5-alkyl-1,3,4-thiodiazole compounds and inhibition of the corrosion of A3 steel in hydrochoric acid solution by 3-phenyl-4-amino-5-mercapto -1,2,4-triazole(PAMT),3-phenyl-6-methyl-s-triazolo[3,4-b][1,3,4]thiadiazoles(PMTT),3H-6-phenyl-s-triazolo[3,4-b][1,3,4]thiadiazoles(HPTT) and 3-phenyl-6H-s- triazolo[3,4-b][1,3,4]thiadiazoles(PHTT) have been investigated using electrochemical impedance spectroscopy (EIS), potentiodynamic polarisation and gravimetric methods. To establish whether inhibition is due to the formation of a film on the A3 steel via adsorption scanning electron photograph was taken. We
