The influence of alloy composition and casting procedure upon the corrosion behaviour of dental alloys: an in vitro study.
The influence of the composition and the casting process upon the electrochemical corrosion of a selection of palladium-based alloys and non-precious metal alloys has been investigated in vitro using an electrochemical method. No influence of the casting process upon the corrosion resistance was observed with palladium-based alloys. Changes in the crystallographic structure effected by the different composition of the alloys were found, the casting process did not cause significant effects. With nickel-chromium alloys rather low corrosion stabilities were observed.
