ABSTRACT
In order to evaluate the corrosion behavior of some dental alloys to be applied as base-metal for PFM, electrochemical technique and metallurgical investigation were used. Potentiodynamic and potentiostatic tests were carried out under deaerated and aerated conditions in 1 percent NaCl solution. The results have shown that Ni-Cr alloy has a superior corrosion resistance under deaerated conditions, whereas Co-Cr alloy has a stronger tendency to passivation under aerated conditions. Fe-Cr alloy has demonstrated a poor performance. The results were analyzed on compositional and microstructural bases
