Abstract
Pure iron, Fe-0.4, and 1.2 wt.%Cu alloys were examined by conducting the electrochemical techniques inthe weakly alkaline solution, pH9, controlled by Ca(OH)2 solution added with 0.02M NaCl. The Rp measured fromac impedance, selected 10 kHz and 10mHz, in weakly alkaline solutions containing chloride ions indicated that theaddition of copper up to 1.2wt.% into the pure iron significantly improved the pitting resistance of iron. In contrastto alloy, the pure iron showed the rapid pitting occurencespotential of pure iron was shifted to less noble value, pitting initiation.
