Trade Analysis of Strength and Wear Resistance of Gold-Based Alloys Containing Modifying Admixtures

The authors of this article have studied physical and mechanical properties of several gold alloys rating 585 and 375. Modern scientific studies demonstrate a significant influence of different modifying admixtures on the properties of goldcontaining all oys. For comparison purposes they've chosen 15 jewelry goldbased alloys with different chemical compositi on and impurities i.e. Ga, Co, B, Si, Zr, Mn, or without them. To conduct the study they've used all available physical and mechanical methods. The alloys were tested for hardness after casting, after aging, the tensile and breaking strength as well as for relative wear resistance. The results of each alloy were analyzed individually and also in comparison with others. The purpose of the study was to identify alloys with the most optimal hardness, strength and wear resistance.
