Abstract
In this study, Ag-Au-Cu-Pd system alloys consisting of 5 or 10 mass% indium were experimentally developed. The mechanical properties in terms of tensile strength, proof stress, elongation, and Vickers hardness were evaluated. The corrosion resistance was evaluated by the amount of released element and the potentiodynamic polarization profiles. Tarnish tests in 0.1 mol/L sodium sulfide were also carried out. The results were compared with commercial silver-palladium-gold alloy and examined comparatively. The mechanical properties of these alloys were as follows: proof stress; 427〜552 MPa, tensile strength; 537〜673 MPa, elongation; 5.1〜8.6%, Vickers hardness; 170〜209. The transpassive potentials of these experimental alloys were 168〜248 mV, and the amounts of released element were 14〜130 μg/cm²・7 days. The addition of indium to Ag-Au-Cu-10 mass%Pd system alloys effectively improves the tensile strength and tarnish resistance. These findings imply that the 37.5 Ag-25 Au-15 Cu-10 Pd-2 Zn-10 In-0.5 Ir alloy is applicable in dental practice.
