The inhibition effect between 3-methy-4-aminocinnamaldehydene-5-mercapto-1 ,2 ,4-triazole Schiff base (short for MACHMT) and cinnamic aldehyde (short for CA) ,3-methy-4-amino-5-mercapto-1 ,2 ,4-triazole(short for MACMT)on Q235 steel in the hydrochloric acid was studied by polarization curves ,electrochemical impedance spectroscopy .The corrosion performance and inhibition mechanism was discussed and compared .Experiments show that stability and inhibition effeciency of cinnamic aldehyde with a 3-methyl-4-amino-5-mercapto-1 ,2 ,4-triazole’s complex system for Q235 carbon steel are higher than the same concentration of seats Schiff base compounds MACHMT .
