“…The tarnishing process is a naturally occurring phenomenon connected to the interaction between silver- and sulfur-containing compounds found within the surrounding environment. Numerous studies have concentrated on incorporating Ag alloy additives to prevent oxidation and tarnishing. , Ag-based coatings hold great promise as a solution to increase antitarnish properties . Therefore, exploring a high improvement in the antitarnish property of incorporating an Ag-based composite is quite a substantial goal.…”

Three-dimensional nanocrystalline Ag–C composites containing a hexagonal diamond structure were produced by electrochemical reduction of acetic acid and electrodeposition of Ag(NO3) (0.01 M) at −1.1 V vs Ag/AgCl at ambient conditions. After applying the negative potential, an ultrathin layer of Ag (<0.1 μm) was first deposited, and subsequently, competitive electrodeposition of Ag and electroreduction of acetic acid resulted in the formation of nanocrystalline Ag–C products on the electrodes. A combination of microscopic, structural, and spectroscopic characterization results reveals that the nanocrystalline Ag–C contains a hexagonal diamond structure with an average crystallite size of 26 nm. The nanodiamond phase remained unchanged throughout 15–140 min reaction time. However, increasing the reaction time, the thickness of nanocrystalline Ag–C films increased to ∼2 μm with some large polyhedra carbon structures. The nanocrystalline Ag–C composites were utilized in the casting process of sterling silver to enhance its antitarnish properties. The antitarnishing of sterling silver upon exposure to a H2S environment was significantly improved by 50% with 0.005 wt % loading of the Ag–C composite.

“…Other metals can be used instead of copper to improve anti-tarnish properties of the basic sterling alloy. These replacement metals include aluminum, germanium, zinc, cadmium etc [7][8][9][10][11][12] which can form passive films to prevent silver from reaction with sulphur.…”

Sterling alloy is widely used in the jewelry industry. Its anti-tarnish property is one of its most important characteristics. In this study, the effect of tin on the corrosion resistance, and tarnish resistance properties of sterling silver alloy were investigated quantized. The difference between anti-corrosion and anti-tarnish properties was investigated in this paper. The tarnish and corrosion resistance of sterling silver improved as tin content increased. However, there was a point at which increasing tin content further led to poor anti-tarnish properties, even though the alloy retained considerable anti-corrosive properties.
