Investigation on the reaction of sulphur with Ag–Cu–Zn-Ge alloy: Experimental and computational study

Silver and its alloys undergo tarnishing with time, which is a black stain on the surface due to the formation of Ag2S. Developing a tarnish resistant Ag alloy was attempted by alloying Ag with elements that form a passive oxide layer on the surface. Germanium is proven to provide better tarnish res...
