STUDIES ON THE EFFECT OF TWO SALEN SCHIFF-BASES ON THE CORROSION OF LOW ALLOY STEEL IN 1M HCL
The corrosion inhibition by two synthesized Schiff -bases of bis-(2-hydroxy-3-methoxy)-l,6-diaminohexane salicyladimine and bis- (2-hydroxy)-1,6-diaminohexane salicyladimine was investigated by weight loss, Tafel polarization and AC impedance on low alloy steel in 1M HC1. The results show that these...
