In vitro corrosion resistance of high-palladium dental casting alloys

摘要

Objective: The objective of this study was to characterize the in vitro corrosion behavior of five high-palladium dental alloys in two media using a potentiodynamic polarization technique. Methods: Potentiodynamic cyclic polarization between-1000 and + 1000 mV (SCE), 12 h open-circuit potential measurement, and Linear polarization were performed on cast specimens of three Pd-Cu-Ga alloys and two Pd-Ga alloys in deaerated 0.09/100 NaCl solution And Fusayama artificial saliva at 37 deg.
