Abstract

The purpose of this study was to give a quantitative analysis for assessing the tarnish resistance of alloys at the artificial saliva, 0.9% NaCI solution and Ringer's solution. In light of development in low-nobility alloys, it is important that tarnish test is standardized to analyse the tarnish properties of the compositions. There are concerns with the long term chemical stability of these alloys and the resistance to tarnish. Chemical stability is a complex problem involving alloy composition, nobility, microstructure and environment.
