Abstract
Corrosion inhibition by some thiourea derivatives of zinc in hydrochloric acid was measured using hydrogen evolution and weight loss techniques. The tested compounds affect the dissolution rate in one of two manners: (a) inhibition throughout all concentrations added and (b) inhibition at lower concentration and acceleration at higher ones. The effect of structural changes in these compounds on their inhibition efficiency has been discussed.
