Study The Ramifications Of Thiadiazole And Schiff-Base Imidaozline Corrosion Inhibition For Steel In 1MHCl Medium And For Copper In NaHCO₃ Medium

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...
