Abstract

We have been carrying out research works to develop Pd-free dental noble alloys from the viewpoint of stable supply of precious metal alloys for crown and bridge restorations to the dental services. Cyclic voltammetry (CV) was carried out on experimental Ag-Au-Pt-Cu low-gold dental alloys to examine their corrosion resistance in a 0.9% NaCl solution. It was found that the Au/Ag atomic ratio is a controlling factor of corrosion resistance.
