Abstract
Emphasis on reduced costs has led to the greater use of economic alloys. Previous work has designed alloys with physical and mechanical properties similar to those of high gold alloys. Evaluation for the degree of corrosion and tarnish are to followed quantitatively by potentiodynamic and spectrophotometer analysis. In the view of the development in low nobility alloys, it is important that such testing be standardized to characterize the corrosion and tarnish properties of the compositions. But there are concerns with the long term chemical stability of these alloys, the resistance to corrosion and tarnish. Chemical stability is a complex problem involving alloy composition, nobility, microstructure and environment.
