Improving mechanical characteristics of a blackened silver alloy used for manufacturing a jewelry, comprises heating and exposing a blackened silver alloy to sulfurous vapors, where alloy is subjected to a niobium contribution

摘要

The method comprises heating and exposing a blackened silver alloy to sulfurous vapors, where alloy is subjected to a niobium contribution. The alloy is present in a shape of yarn, cut in small pieces, placed inside a crucible containing 2.50 g of sulfur flower per 150 g of alloy, and heated at a melting point and poured into an ingot mold.
