摘要: Abstract The electrode behaviour of spectroscopically pure Fe, steel samples containing 0·15–1·3%C and grey cast Fe in aerated 0·1M solutions NaNO2, Na benzoate ZnSO4, 0·01M quinoline saturated CaCO3 has been studied. anodic (and cathodic) these under potentiostatic or galvanostatic conditions followed de-aerated NaNO2 ZnSO4 solutions. It shown that inhibitors are more sensitive to changes the C-content than cathodic inhibitors, being almost indifferent changes. protective nature cubic oxide formed is less efficient presence separate phases ferrite, carbide graphite its absence. Quinoline preferentially adsorbed on phases. effectiveness (in situ) precipitated Ca(OH)2 blocking sites counteracted by
