Effect of 4‐benzylidene, 3‐methyl. 5‐oxo‐1‐phenyl phyrazoline derivatives on the corrosion of aluminium in HC1 solutions

Abstract

The effect of some pyrazoline derivatives as inhibitors on the dissolution of A1 in 2 mol.L−1 HC1 has been studied by weight‐loss, galvanostatic polarization, polarographic and scanning electron microscopy methods. Additions of Cu2+ Co2+ or Ni2+ ions increases the efficiency of the inhibitors.
