CORROSION INHIBITION OF AA6061 AND AA6063 ALLOY IN HYDROCHLORIC ACID MEDIA BY SCHIFF BASE COMPOUNDS

N, N'-bis (Salicylidene)-1, 4-Diaminophenelyne (SDP) and N, N'-bis (3-Methoxy Salicylidene)-1, 4 Diaminophenelyne (MSDP) were synthesized, and their molecular structure were determined by FT-IR and ¹H NMR. The corrosion inhibitions of these compounds on AA6061 in 1M Hydrochloric acid were...
