AI Technical Summary
Existing silver alloy jewelry cannot simultaneously meet the requirements of low cost, high mechanical performance, and resistance to sweat corrosion. Furthermore, traditional alloying designs neglect the mechanical properties of the material, making it prone to scratches and corrosion during wear.
By adding conventional metallic elements such as Cu, Al, Zn, Sn, and In to silver alloys and employing solution-aging heat treatment to form uniformly dispersed strengthening phases, a stable surface oxide film is formed, thereby improving the alloy's hardness and resistance to discoloration.
The prepared silver alloy exhibits significantly improved microhardness, excellent scratch resistance, and more than twice the tarnish resistance of Stirling silver, making it suitable for use in silver jewelry.
