Cyclic polarization technique was used to determine the corrosion susceptibility of some Pd-enriched amalgams as compared with the conventional and high-copper ones. Different oxidation and reduction peaks and their corresponding current intensities were determined in each case. Corrosion indices I and II were also calculated. Pd-enriched amalgams have shown lower corrosion susceptibility than conventional or unicompositional high-copper amalgams. A role was attributed to the alloy composition and the relative cathodic (reduction) current available.
