Development of new ternary silver alloys resistant to sulfidation

Development of new ternary silver alloys resistant to sulfidation

Objective

Silver alloys are advanced metals whose demand is based on 2 main pillars: 'electronic industry' and 'jewellery and silverware'. However, a major problem of silver alloys is that they are prone to sulfidation. There is also a strong potential to replace noble metals (gold and palladium) by silver alloys resistant to sulfidation, taking into account that silver cost 30 times less than Gold. In the field of Jewels and silverware, silver tend to darken which is aesthetically unacceptable. Ternary silver alloys have hardly been investigated but showed better resistance to sulfidation and therefore will be studied in this project. Ternary silver alloys will be manufactured by co-sputerring with 3 targets. Developed alloys should fulfill technical specifications from the electric & silverware industry
