“…This indicates that at the deficient concentrations of the sulfide ions, typical for the atmospheric corrosion, the corrosion rates could be even lower and suggests that the investigated alloys are very stable over a long period regarding tarnish. Comparison of obtaining results with previously investigated [28] alloys in Ag-Cu-Zn-Si system are presented in Figure 1.…”

This paper presents investigations of aluminum addition influence on the corrosion characteristics of the sterling silver Ag-Cu-Zn-Si alloys. The procedure for obtaining Ag-Cu-Zn-Al-Si alloys in small ranges of predefined composition was also presented. Open circuit potential measurements, linear polarization resistance method and potentiodynamic polarization tests were employed to determine corrosion characteristics of the alloys. The materials were tested in a 0.01M sodium sulfide solution. It was shown that the addition of aluminum improves sulfidization resistance and corrosion characteristics. Best results are achieved for the alloy with the following composition 92.5% Ag, 1.9% Cu, 3.7% Zn, 1.6% Al and 0.3% Si.

“…Previous research of authors [27,28] was focused on investigating the influence of silicon addition to standard sterling silver alloy and replacement of copper with silicon in the range from 0.05 to 0.3% [27] and additionally replacement of 1% of copper with zinc [28].…”
