N,N'-Disubstituted hydrazines and their effect on corrosion-electrochemical behaviour of steel

摘要

Corrosive and electrochemical behaviour of the steel 20 in 0.1 M HCl in the presence of N, N'-disubstituted hydrazines has been studied. The protection effectiveness was characterized by inhibition coefficient of electrochemical corrosion and particular contributions of inhibiting effects in the total coefficient of corrosion retardation. The regularities of anticorrosion activity, depending on the polar properties of substituent in N and N' nitrogen atoms of the hydrazine, have been determined.
